Geometry QA#2 Review

Front

What is the translation of triangle ABC to triangle A'B'C' if the transformation is (x - 2, y + 9)?

Back

The triangle is translated 2 units to the left and 9 units up.

Front

How do you find the slope of a line perpendicular to y = 3/2x + 6?

Back

The slope of the given line is 3/2. The slope of a line perpendicular to it is the negative reciprocal, which is -2/3.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

If y = -2/3x + 2 and y = 3/2x + 9, what can be said about their relationship?

Back

These lines are perpendicular.

Front

What is the AAS triangle congruence theorem?

Back

AAS stands for Angle-Angle-Side, which states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the SAS triangle congruence theorem?

Back

SAS stands for Side-Angle-Side, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the ASA triangle congruence theorem?

Back

ASA stands for Angle-Side-Angle, which states that if two angles and the included side of one triangle are equal to two angles and the corresponding included side of another triangle, the triangles are congruent.

Front

What is the AAA triangle congruence theorem?

Back

AAA stands for Angle-Angle-Angle, which states that if all three angles of one triangle are equal to all three angles of another triangle, the triangles are similar, but not necessarily congruent.

Front

How do you determine the coordinates of a point after a translation?

Back

To determine the new coordinates, add the translation values to the original coordinates.

Front

What is the formula for 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).
