Front

What are the coordinates of point H' after reflecting point H(3, 4) across the x-axis?

Back

(3, -4)

Front

What is the Reflexive Property in geometry?

Back

The Reflexive Property states that any geometric figure is congruent to itself.

Front

What is the SSS (Side-Side-Side) Congruence Postulate?

Back

The SSS Postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

Front

How do you find the missing angle in a triangle if two angles are known?

Back

Subtract the sum of the known angles from 180 degrees.

Front

What is the equation of a line parallel to y = 4x + 3 that passes through the point (-4, -5)?

Back

y = 4x + 11

Front

If R is between C and A, and CR = 2x + 15, RA = 3x + 17, and CA = 37, how do you find x?

Back

Set up the equation: CR + RA = CA, then solve for x.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the Pythagorean Theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they never intersect and are always the same distance apart.

Front

What is the definition of a congruent triangle?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.
