What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle. It is parallel to the third side and its length is half the length of that side.

Front

If QR is a midsegment of triangle FGH, what can be said about the lengths of QR and side GH?

Back

QR is half the length of side GH, and QR is parallel to GH.

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 measure of an unknown angle in a triangle?

Back

To find an unknown angle, subtract the sum of the known angles from 180 degrees.

Front

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

Back

In an isosceles triangle, the angles opposite the equal sides are also equal.

Front

Define a triangle's base angles. What are they?

Back

Base angles are the angles opposite the base of a triangle. In an isosceles triangle, these angles are equal.

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

If the base of a triangle is 10 units and the height is 5 units, what is the area?

Back

Area = 1/2 * 10 * 5 = 25 square units.

Front

What is the definition of a triangle?

Back

A triangle is a polygon with three edges and three vertices.
