Geometry Semester 1 Exam Review

Front

What is the distance formula in geometry?

Back

The distance formula is given by: d = √((x2 - x1)² + (y2 - y1)²), where (x1, y1) and (x2, y2) are the coordinates of two points.

Front

What is a vertical angle?

Back

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

Front

What does adjacent angles mean?

Back

Adjacent angles are two angles that share a common side and a common vertex but do not overlap.

Front

How do you find the distance between two points on a coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the sum of the angles in a triangle?

Back

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

Front

What is a complementary angle?

Back

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

Front

What is a supplementary angle?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is given by the formula: Area = length × width.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 × base × height.
