A point has no size
Sharper pencil, smaller dot.
The dot on your page is only a signal. What it stands for holds one position and takes up no room. Sharpen the pencil and you come closer to the truth of it.

The whole idea, one bite at a time
Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Labelling points
Capitals keep the dots apart.
Three unnamed dots are hard to discuss. Give each one a capital letter and the difficulty vanishes. Now you can say point H and everyone looks at the same spot.
Line segment
Clipped at both ends.
Two ends are marked and the path between them is straight. Nothing carries on past either end. That is the whole of it.
What an angle is made of
Two rays, one shared start.
Send two rays out from the same dot in different directions. That figure is an angle. The shared dot is the vertex and the two rays are the arms.
Reading an angle's name
Middle letter, corner point.
In angle MQR the corner is at Q, because Q sits in the middle. Angle RQM says exactly the same thing. Only the outer letters may be swapped.
Size means turning
How far did it swing?
Start with both arms together and swing one round to its place. The further it had to travel, the larger the angle. That is the whole meaning of a bigger angle.

1
Points, Lines, Segments and Rays
The four starting pieces of plane geometry: a point that marks a spot, a segment that stops, a line that never stops, and a ray that stops only at one end.
- A point fixes one position. It has no length, no width and no height of its own.
- We label points with single capital letters so that we can talk about them without confusion.
- A line segment is the straight path between two marked ends, and it is the shortest route between them.

Angles, and Comparing Them
What an angle is made of, how its name is written, why turning is what we are measuring, and three ways of deciding which of two angles is bigger.
- An angle is made by two rays that share the same starting point.
- The shared starting point is the vertex, and the two rays are the arms.
- A three letter name always keeps the vertex letter in the middle, so angle MQR has its vertex at Q.

Special Angles and the Degree
The straight angle, the right angle and the whole turn, how a circle cut into 360 equal parts gives us the degree, and why that odd number 360 was chosen.
- When the two arms of an angle fall in a straight line, the angle is a straight angle, and it is half a whole turn.
- Folding a straight angle so that one arm drops onto the other gives two equal angles, and each of these is a right angle.
- A right angle is exactly half of a straight angle and exactly a quarter of a whole turn.

Measuring with a Protractor, and the Angle Bisector
How the two scales on a protractor work, where the centre and the zero line must sit, what to do when no arm lies on zero, and how halving an angle gives its bisector.
- A protractor is a half circle divided into 180 equal unit parts, with long marks every ten degrees.
- Two sets of numbers are printed on it, one rising from the right and one rising from the left, so that either arm can be used as the base.
- The centre mark of the protractor must sit exactly on the vertex of the angle before anything is read.

Drawing Angles; Acute, Obtuse and Reflex
Drawing an angle of a given size with a protractor, estimating before measuring, and sorting every measure from 0 to 360 into acute, right, obtuse, straight and reflex.
- To draw an angle, first rule the base arm, then set the protractor with its centre on the vertex and the base arm on the zero line.
- Mark the required number on the scale that reads zero along your base arm, then join that mark to the vertex with a ruler.
- Estimating first and measuring afterwards builds a feel for size, and the gap between the two is the part worth studying.

❓ Leveled MCQ practice
Try the smart MCQs from this kit
145 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Sara sharpens her pencil and the dot she draws gets thinner. What idea is this pointing at?
Beginner
A That a point stands for a position and has no size
B That a sharper pencil will always draw a straighter and truer line
C That a point has a width, and that width is measured in millimetres
D That thin dots are easier to rub out than the thick ones are
Show answer & explanation
That a point stands for a position and has no size
The thinner the mark, the closer it comes to standing for a bare position.
Three dots sit on a page with no labels. What is the first difficulty this causes?
Beginner
A The dots become hard to see, because unlabelled dots are drawn fainter
B The dots cannot be talked about one at a time
C The dots stop counting as points until a letter is written beside them
D The dots have to be joined up before anybody is allowed to name them
Show answer & explanation
The dots cannot be talked about one at a time
Without names there is no way to say which dot you mean.
A drawing shows a straight path with a dot at each end and nothing beyond. What is it?
Beginner
A A ray
B A straight line
C A line segment
D A point
Show answer & explanation
A line segment
Two marked ends and no arrowheads is the picture of a segment.
A straight path drawn with an arrowhead at each end is called a ____.
Beginner
A segment
B ray
C point
D line
Show answer & explanation
line
Arrows at both ends say the figure carries on both ways, which is a line.
