Exploring Triangle Sum and Exterior Angle Theorem

What is the definition of a triangle?

How many congruent sides does an equilateral triangle have?

According to the exterior angle theorem, the measure of an exterior angle of a triangle is equal to:

If a triangle has two congruent sides, it is classified as:

A triangle with sides of lengths 5, 7, and 10 is classified as:

What type of triangle has one angle that is exactly 90 degrees?

A triangle with all angles less than 90 degrees is called:

What is the sum of all angles in a triangle?

If one angle of a triangle is 90 degrees and another is 35 degrees, what is the measure of the third angle?

Using the exterior angle theorem, if one exterior angle is 158 degrees and one of the nonadjacent interior angles is 70 degrees, what is the measure of the other nonadjacent interior angle?
