Question

1. name all the right angles and straight angles in the given image.

right angles
straight angles

Explanation:

Step1: Recall the definition of a right angle

A right angle is an angle that measures \(90^{\circ}\). In the given figure, \(\angle CFD = 90^{\circ}\).

Step2: Recall the definition of a straight angle

A straight angle is an angle that measures \(180^{\circ}\). \(\angle AFD\) and \(\angle AFC\) are straight angles as they form a straight line.

Answer:

Right Angles: \(\angle CFD\)
Straight Angles: \(\angle AFD\), \(\angle AFC\)
