What is an isosceles triangle?

Back

An isosceles triangle is a triangle with at least two sides of equal length and the angles opposite those sides are also equal.

What are the properties of a line in geometry?

Back

A line has infinite points, one dimension, and extends in opposite directions forever.

Front

How do you find the length of the sides of a triangle given two sides?

Back

Use the Pythagorean theorem if it's a right triangle, or apply the triangle inequality theorem.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What does reflection mean in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the difference between a line and a line segment?

Back

A line extends infinitely in both directions, while a line segment has two endpoints.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, such as translation, rotation, reflection, or dilation.

Front

How do you identify the hypotenuse in a right triangle?

Back

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

Front

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

Back

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