Geometry Chapter 1 Review

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 coplanar point?

Back

Coplanar points are points that lie on the same plane.

Front

How do you find the missing angle in a triangle?

Back

To find the missing angle, subtract the sum of the known angles from 180 degrees.

Front

What is the formula for the distance between two points (x1, y1) and (x2, y2)?

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the value of x if 2x + 6 = 14?

Back

x = 4.

Front

Define a line segment.

Back

A line segment is a part of a line that is bounded by two distinct endpoints.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint called the vertex.

Front

What is the difference between acute, obtuse, and right angles?

Back

Acute angles are less than 90 degrees, right angles are exactly 90 degrees, and obtuse angles are greater than 90 degrees but less than 180 degrees.

Front

What is the relationship between parallel lines and angles?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal.

Front

How do you calculate the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).
