Triangle Warm Up 1

Front

What is the Triangle Sum Theorem?

Back

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

Front

Solve for k: 3k + 6 = 42.

Back

k = 12.

Front

If angle A = 44°, what is the measure of angle B if angle C = 96°?

Back

Angle B = 180° - (44° + 96°) = 40°.

Front

Find the measure of the missing angle in a triangle if the other two angles are 70° and 80°.

Back

The missing angle is 30°.

Front

Which set of angles can form a triangle? 45°, 65°, 70° or 150°, 110°, 100°?

Back

The angles 45°, 65°, 70° can form a triangle.

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60°.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.

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 formula to find the area of a triangle?

Back

Area = 1/2 * base * height.

Front

If the angles of a triangle are 50°, 50°, and x°, what is the value of x?

Back

x = 80°.
