HON Geometry Semester 1 Review 2021-2022

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be proven using criteria such as SSS, SAS, or ASA.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If two sides of a triangle are 17 meters and 12 meters, what is the range of possible lengths for the third side?

Back

5 < x < 29.

Front

What does SSS similarity mean in triangles?

Back

SSS similarity means that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the definition of an altitude in a triangle?

Back

An altitude is a perpendicular segment from a vertex to the line containing the opposite side.

Front

At what degree do altitudes hit the ground?

Back

Altitudes hit the ground at 90 degrees.

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What does it mean for two triangles to be similar?

Back

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

Front

How can you determine if two triangles are congruent using SAS?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent (SAS).

Front

What is the relationship between the angles in a triangle?

Back

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