Question

Name an example of an acute angle, right angle, and straight angle according to their angle measures

Answer 1

Acute: anything less than 90 but greater than 0

so, m<CAD

right: angles at exactly 90 degrees, so m<AEC,

and obtuse angles are anything greater than 90 but less than 180 degrees,

so CDA (you can tell by the picture that it is bigger than 90- 90 degrees is exactly perpendicular)
