Back

Triangles that have the same shape but may have different sizes; their corresponding angles are equal and their corresponding sides are in proportion.

Front

How do you find the volume of a sphere?

Back

Volume = (4/3)πr³, where r is the radius of the sphere.

What is the value of x if the angles in a triangle are 50°, 65°, and x°?

Back

x = 65° (the sum of angles in a triangle is 180°).

Front

How do you calculate the area of a circle?

Back

Area = πr², where r is the radius of the circle.

What does SAS (Side-Angle-Side) mean in triangle congruence?

Back

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.

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the Transitive Property in geometry?

Back

If a = b and b = c, then a = c.

Front

How do you find the circumference of a circle?

Back

Circumference = 2πr, where r is the radius.

Front

What is the definition of vertical angles?

Back
