What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths and all three angles are of different measures.

Front

What is an acute triangle?

Back

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

Front

What is a right triangle?

Back

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

Front

What is an isosceles triangle?

Back

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

Front

How do you find the length of a segment formed by connecting midpoints of a triangle?

Back

The length of the segment connecting the midpoints of two sides of a triangle is half the length of the third side.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

How do you determine the type of triangle based on its angles?

Back

- If one angle is 90 degrees, it's a right triangle. - If all angles are less than 90 degrees, it's an acute triangle. - If one angle is greater than 90 degrees, it's an obtuse triangle.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: \( A = \frac{1}{2} \times base \times height \) .

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): \( c^2 = a^2 + b^2 \) .

Front

What is the definition of a triangle's median?

Back

A median of a triangle is a line segment joining a vertex to the midpoint of the opposite side.
