Geometry Final Exam S1 Review (second 15 questions)

Front

What is the translation rule for moving a point 7 units to the right and 1 unit down?

Back

The translation rule is: (x, y) → (x + 7, y - 1).

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

How do you find the value of an unknown angle in a triangle?

Back

Use the fact that the sum of the angles in a triangle is 180 degrees. Subtract the known angles from 180 to find the unknown angle.

Front

What type of triangle has all sides of different lengths?

Back

A scalene triangle has all sides of different lengths.

Front

What is an exterior angle of a triangle?

Back

An exterior angle is formed by one side of the triangle and the extension of an adjacent side. The exterior angle is equal to the sum of the two opposite interior angles.

Front

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle has at least two sides that are equal in length.

Front

How do you calculate the measure of an exterior angle?

Back

The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.

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

What is the relationship between the angles in an isosceles triangle?

Back

In an isosceles triangle, the angles opposite the equal sides are also equal.
