What does congruent mean in geometry?

• Figures having the same shape and size.

• A transformation by turning a figure about a center point or axis.

• A transformation moving every point in a figure in the same direction and distance.

• A transformation producing a mirror image across a line.

What is an isosceles triangle?

• A triangle containing an interior right angle

• A triangle that contains at least two equal length sides and two equal interior angle (base angle) measures.

• A line, ray, or line segment that cuts an angle into two equal parts.

• A line, ray, or line segment that cuts a line segment into two equal parts.

What does the Perpendicular Bisector Theorem state?

• If point P is in the interior of ∠KWT, then m∠KWP + m∠PWT = m∠KWT

• If a point is on the perpendicular bisector of a line segment, then it is equidistant from the endpoints of the line segment.

• If three points, K, Y, and C, are collinear and Y is in between K and C, then KY + YC = KC

• The points of a line can be placed in a one-to-one correspondence with the real numbers such that the distance between two distinct points is the absolute value of the difference of the corresponding real numbers.

• A segment that represents moving from point A to point B.

• A segment that represents moving from point B to point A.

• A segment that represents moving from point C to point D.

• A segment that represents moving from point D to point C.
