18 Weeks of School TEST

Front

What is the measure of the missing angle if the other two angles are 90° and 40°?

Back

50°

Front

What type of triangle has two sides of equal length?

Back

Isosceles triangle

Front

If angle A is 40° and angle B is 50°, what is angle C in a triangle?

Back

Angle C = 90° (since the sum of angles in a triangle is 180°)

Front

What is the measure of angle C if angle A is 64° and angle B is 116°?

Back

Angle C = 180° - (64° + 116°) = 0° (not possible, check angles)

Front

What is the measure of angle 1 if it is complementary to angle 2 which is 73°?

Back

Angle 1 = 90° - 73° = 17°

Front

What is the definition of an equilateral triangle?

Back

A triangle with all three sides of equal length and all angles measuring 60°.

Front

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

Back

180°

Front

If one angle of a triangle is obtuse, what can be said about the other two angles?

Back

They must be acute (less than 90°).

Front

What is the definition of a scalene triangle?

Back

A triangle with all sides of different lengths.

Front

If angle A is 30° and angle B is 60°, what is angle C in a triangle?

Back

Angle C = 90° (since the sum of angles in a triangle is 180°)
