What is an acute triangle?

Back

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

Front

What does ΔEDF ≅ Δ____ imply?

Back

It implies that the triangles are congruent, meaning they have the same shape and size. The correct answer is BAC.

Front

How do you find the measure of an angle in a triangle?

Back

You can use the properties of triangles, such as the sum of angles in a triangle equals 180 degrees, or apply trigonometric ratios if applicable.

Back

x=8.

Front

What is the definition of a right triangle?

Back

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

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning their corresponding sides and angles are equal.

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.

Front

What is the definition of 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.
