Geometry Semester 1 Exam 2024

Front

What are complementary angles?

Back

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

Front

If Angle A = 7x + 1 and Angle B = 5x - 7, how do you find the measures of Angle A and Angle B if they are complementary?

Back

Set up the equation: (7x + 1) + (5x - 7) = 90. Solve for x, then substitute back to find A and B.

Front

What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

Which property states that if A = B and B = C, then A = C?

Back

This is known as the Transitive Property.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle with at least two sides of equal length.

Front

How do you find the third vertex of an isosceles right triangle given two vertices?

Back

Use the Pythagorean theorem and the properties of right triangles to determine the possible coordinates.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

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

Back

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

Front

What is the definition of the reflexive property?

Back

The reflexive property states that any quantity is equal to itself (e.g., A = A).

Front

What is the definition of the symmetric property?

Back

The symmetric property states that if A = B, then B = A.
