Front

What is the formula for calculating the height of a tree using similar triangles?

Back

Height = (Height of kite) * (Distance from tree) / (Distance from kite to tree top)

Front

Define 'hypotenuse' in a right triangle.

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides: a² + b² = c².

Front

How do you round a number to the nearest whole number?

Back

Look at the digit to the right of the target digit. If it's 5 or more, round up; if it's less than 5, round down.

Front

What is the definition of 'perimeter'?

Back

The perimeter is the total distance around a two-dimensional shape.

Front

How do you find the distance between two points on a coordinate plane?

Back

Use the distance formula: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the definition of 'area' in geometry?

Back

Area is the amount of space inside a two-dimensional shape, measured in square units.

Front

What is the relationship between the sides of a 30-60-90 triangle?

Back

In a 30-60-90 triangle, the lengths of the sides are in the ratio 1:√3:2.

Front

How do you calculate the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is the definition of 'volume' in geometry?

Back

Volume is the amount of space occupied by a three-dimensional object, measured in cubic units.
