Front

What is the measure of angle CEI if m∠CEI = 34°?

Back

m∠CEI = 34°

Front

What is the measure of the indicated angle if the options are 95, 85, 35, 45 and the answer is 45?

Back

The measure of the indicated angle is 45°.

Front

If a 3ft tall statue casts an 8ft shadow, how long will the shadow of a 6ft tall sign be?

Back

The shadow of the 6ft tall sign will be 16ft.

Front

What does it mean for triangles to be similar, such as ΔABC ∼ ΔANM?

Back

Triangles are similar if their corresponding angles are equal and their sides are in proportion.

Front

What is the measure of angle ECI if m∠ECI = 73°?

Back

m∠ECI = 73°.

Front

Define similar triangles in geometry.

Back

Similar triangles have the same shape but may differ in size; their corresponding angles are equal and their sides are proportional.

Front

What is the formula for finding the length of a shadow based on similar triangles?

Back

The length of the shadow can be found using the ratio of the heights of the objects to the lengths of their shadows.

Front

What is the relationship between angles in a triangle?

Back

The sum of the interior angles in a triangle is always 180°.

Front

How do you find the measure of an angle when given two other angles in a triangle?

Back

Subtract the sum of the two known angles from 180°.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90°.
