GEOCCR 4.6 Isosceles and Equilateral Triangles

Front

What is an acute triangle?

Back

An acute triangle is a triangle in which all three angles are less than 90 degrees.

Front

What type of triangle has at least two sides of equal length?

Back

An isosceles triangle 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 are equal, each measuring 60 degrees.

Front

What does it mean for a triangle to be equiangular?

Back

A triangle is equiangular if all its angles are equal.

Front

How can you classify a triangle with one angle greater than 90 degrees?

Back

A triangle with one angle greater than 90 degrees is classified as an obtuse triangle.

Front

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

Back

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

Front

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

Back

In a triangle, the largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.

Front

What is the formula for finding the area of a triangle?

Back

The area of a triangle can be found using the formula: Area = 1/2 * base * 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 is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

Front

What is a right triangle?

Back

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