GEOMETRY FINAL Review

Front

What does AA stand for in triangle similarity?

Back

AA stands for Angle-Angle similarity, which states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

Front

What is the property of a parallelogram regarding opposite sides?

Back

In a parallelogram, opposite sides are equal in length and parallel.

Front

How do you find the slope of a line?

Back

The slope (m) of a line is calculated as the change in y divided by the change in x (m = Δy/Δx).

Front

What is the slope of a line parallel to a line with slope 3/4?

Back

The slope of a line parallel to a line with slope 3/4 is also 3/4.

Front

What are opposite reciprocals in terms of slopes?

Back

Opposite reciprocals are two numbers whose product is -1; for example, if one slope is m, the opposite reciprocal is -1/m.

Front

What happens to the coordinates of a point (x,y) when translated by (x,y) --> (x+3, y-2)?

Back

The x-coordinate increases by 3 and the y-coordinate decreases by 2.

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 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 Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is a transversal line?

Back

A transversal line is a line that intersects two or more other lines at distinct points.
