Geometry: 1st Sem exam Review

Front

What do the angles in an equilateral triangle measure?

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

What is the slope of a line with a rise of 4 and a run of 3?

Back

The slope of the line is 4/3.

Front

Solve for x in the equation: 2x + 5 = 75

Back

x = 35.

Front

What slope is perpendicular to a line with a slope of 5/8?

Back

The slope that is perpendicular is -8/5.

Front

What equation would you use to find the value of x in a triangle where the angles sum to 180 degrees?

Back

Use the equation: 2x - 6 + 7x + 4 = 180.

Front

Define an equilateral triangle.

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal, measuring 60 degrees each.

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.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

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

Define a right triangle.

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
