### QUESTION 1 of 10

In this worksheet, you must measure angles and say which type of angle they are.

Example:

Measure these angles, using a protractor.  Say whether they are acute (less than 90°), a right angle (= 90°), obtuse (between 90° and 180°) or reflex (more than 180°).

An angle measures the rotation of one line segment on to another. Angles are measured in degrees, °.

 AB is turned through 50° to coincide with AC. The angle is labelled BAC. A quarter rotation measures 90° and is marked with a square. A half rotation measures 180°. A complete rotation measures 360°.

Measure this angle using a protractor.

In the first answer box, state whether this angle is acute, obtuse, right angle or reflex.

In the second answer box, state its size in degrees (just write the number).
