Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of all interior angles in a triangle is 180°.

Front

What is the minimum possible length of the third side of a triangle with sides of length 5 and 5?

Back

The minimum possible length is 1, and the maximum possible length is 10. The third side must be less than the sum and greater than the difference of the other two sides.

Front

What is the maximum possible length of the third side of a triangle with sides of length 5 and 5?

Back

The maximum possible length is 10, as it must be less than the sum of the other two sides.

Front

If one angle of a triangle is 90°, what type of triangle is it?

Back

It is a right triangle.

Front

What is the sum of the interior angles of a quadrilateral?

Back

The sum of the interior angles of a quadrilateral is 360°.

Front

How do you find the measure of an exterior angle of a triangle?

Back

The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.

Front

What is the relationship between the angles in an isosceles triangle?

Back

In an isosceles triangle, the angles opposite the equal sides are also equal.

Front

What is a polygon?

Back

A polygon is a closed figure formed by a finite number of straight line segments.
