Check
What do all the angles in a triangle add up to?
180
What would be an angle that measures 139 degrees?
Obtuse
If a triangle has a right angle and an angle that measures 38, what is the missing angle?
52 degrees
What is an angle that is greater than obtuse but smaller than reflex?
Straight angle
If a quadrilateral has 360 degrees when all angles are added, and the two bottom angles are 40 each, what would be the two top angles, if they are equal?
140 degrees
Start with a straight angle, subtract 40 degrees, add 10 degrees, then multiply that number by two. Divide it by three. What angle is that?
If a triangle has 180 degrees in total, and a quadrilateral has 360 degrees in total, following this pattern how many degrees does an octagon?
900
