What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

How do you calculate the perimeter of a triangle?

Back

The perimeter of a triangle is calculated by adding the lengths of all three sides: P = a + b + c.

What is the definition of an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

What is the relationship between the angles in an isosceles triangle?

Back

In an isosceles triangle, the angles opposite the equal sides are also equal.

Front

What is the formula for the area of a triangle?

Back

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

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the sine function in a right triangle?

Back

In a right triangle, the sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse: sin(A) = opposite/hypotenuse.

Front

What is the formula for the volume of a cone?

Back

The volume of a cone is given by the formula: V = (1/3) * π * r² * h, where r is the radius and h is the height.

Front

How do you express a linear relationship between length and width?

Back

A linear relationship can be expressed as l = 2w - 3, where l is the length and w is the width.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.
