isosceles and equilateral triangles

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles measure 60 degrees.

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

How do you find the length of a side in an isosceles triangle when given the base and height?

Back

You can use the Pythagorean theorem to find the length of the equal sides by creating a right triangle with half the base as one leg and the height as the other leg.

Front

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

Back

The angles opposite the equal sides are also equal.

Front

How do you classify a triangle based on its angles?

Back

Triangles can be classified as acute (all angles less than 90°), right (one angle equal to 90°), or obtuse (one angle greater than 90°).

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 equiangular triangles?

Back

Equiangular triangles are triangles in which all three angles are equal, which also means they are equilateral.

Front

How do you find the missing angle in a triangle?

Back

To find the missing angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the relationship between the sides and angles in a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side; conversely, the smaller the angle, the shorter the opposite side.
