What is the formula for the equation of a circle?

Back

The equation of a circle with center (h, k) and radius r is given by: (x - h)² + (y - k)² = r².

What is the value of KJ if KJ = 13?

Back

KJ is equal to 13.

Front

What does congruence mean in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.

Front

How do you find the measure of an angle in a triangle?

Back

The sum of the angles in a triangle is always 180°. To find an unknown angle, subtract the sum of the known angles from 180°.

Front

What is the relationship between similar triangles?

Back

Similar triangles have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

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 the formula for the area of a triangle?

Back

The area (A) of a triangle can be calculated using the formula: A = 1/2 * base * height.

Front

What is the definition of a radius in a circle?

Back

A radius is a line segment from the center of the circle to any point on the circle.

Front

How do you determine if two triangles are congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal. This can be proven using criteria such as SSS, SAS, ASA, AAS, or HL.

Front

What is the formula for the circumference of a circle?

Back

The circumference (C) of a circle is given by the formula: C = 2πr, where r is the radius.
