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 the ratios of the lengths of their corresponding sides are proportional.

How do you find the height of a person using similar triangles?

Back

You can set up a proportion using the heights and corresponding shadow lengths of two similar triangles to solve for the unknown height.

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 are the conditions for three lengths to form a triangle?

Back

The sum of the lengths of any two sides must be greater than the length of the third side.

Front

What type of triangle is formed by the lengths 9, 12, and 15?

Back

Yes, these lengths form a right triangle because 9² + 12² = 15².

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle in which one of the angles is greater than 90 degrees.

Front

How do you classify a triangle based on its angles?

Back

Triangles can be classified as acute (all angles < 90°), right (one angle = 90°), or obtuse (one angle > 90°).

Front

What is the decimal equivalent of 1/8?

Back

.1250

Front

What is the significance of the Pythagorean Theorem in geometry?

Back

It is used to determine the lengths of sides in right triangles and is fundamental in various applications in geometry.

Front

What is a right triangle?

Back

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