Question

EXERCISE 5.4
what is the measure of (1) a right angle? (in) a straight angle?
Say True or False :
(a) The measure of an acute angle <90°
(1) The measure of an obtuse angle <90°
(c) The measure of a reflex angle > 180°.
(d) The measure of one complete revolution = 360°.
d) If mZA = 53° and mZB = 35º, then mZA >mB.
Write down the measures of
(a) some acute angles. (b) some obtuse angles.
(give at least two examples of each).
Measure the angles given below using the Protractor and write​

Answer 2

Answer:

Measure of:

Right angle = 90°

Straight angle = 180°

True or false:

(a) The measure of an acute angle <90° : TRUE

(b) The measure of an obtuse angle <90° : FALSE

(c) The measure of a reflex angle > 180° : TRUE

(d) The measure of one complete revolution = 360° : TRUE

d) If mZA = 53° and mZB = 35º, then mZA >mZB : TRUE

Examples of:

Acute angle: 20°, 30°, 50°

Obtuse angle: 100°, 150°, 120°

Hope it Helps!!
