Question

Here are two shapes drawn on a square grid.

For each shape, write the number of right angles it has.

Answer 1

1, 0

Explanation:

What is an angle?

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, making the sides of the angle.

What types of angles are there?

There are right angles (exactly 90 degrees), acute angles (less than 90 degrees), obtuse angles (more than 90 degrees), and reflex angles (more than 180 degrees).

If we know that a right angle is equal to 90°, we know that it is
`(1)/(4)` of a full turn, meaning that it will make both rays (or lines) perpendicular to each other.

Looking at the first shape, we can see it only has one right angle, and there are no right angles in the second shape.
