Front

What is the rule for rotating a figure 270° counter-clockwise about the origin?

Back

(x, y) → (y, -x)

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which can be determined by comparing their corresponding sides and angles.

Front

Identify the transformation represented by (x+8, y+4).

Back

This transformation indicates a translation of the figure 8 units to the right and 4 units up.

Front

What is a median in a triangle?

Back

A median is a line segment that connects a vertex of the triangle to the midpoint of the opposite side.

Front

How do you list the sides of a triangle from shortest to longest?

Back

Order the sides based on their lengths, from the smallest to the largest.

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, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides: a² + b² = c².

Front

What is the difference between rotation and reflection in geometry?

Back

Rotation turns a figure around a point, while reflection flips a figure over a line.

Front

What is the definition of similar triangles?

Back

Similar triangles have the same shape but may differ in size; their corresponding angles are equal and their corresponding sides are proportional.

Front

What is the formula for the circumference of a circle?

Back

Circumference = 2 * π * radius.
