Segments of Triangles Review

Front

What is a segment in a triangle?

Back

A segment in a triangle is a straight line that connects two points on the triangle, typically referring to the sides of the triangle.

Front

What is the Triangle Sum Theorem?

Back

The Triangle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

How do you find the length of a missing side in a triangle?

Back

To find the length of a missing side in a triangle, you can use the Pythagorean theorem for right triangles or the Law of Cosines for non-right triangles.

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 the Law of Cosines?

Back

The Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles: c² = a² + b² - 2ab*cos(C).

Front

What is a right triangle?

Back

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

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 are equal to 60 degrees.

Front

What is the definition of a median in a triangle?

Back

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

Front

What is the definition of an altitude in a triangle?

Back

An altitude of a triangle is a perpendicular segment from a vertex to the line containing the opposite side.
