Geometry 5.1- 5.4 Flashcard

Front

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

What is the measure of an angle in a right triangle?

Back

In a right triangle, one angle measures 90 degrees. The other two angles must add up to 90 degrees.

Front

If AC = 42, what is the length of the midsegment DF?

Back

The length of DF is 21, which is half of AC.

Front

How do you determine the largest side in a triangle?

Back

The largest side in a triangle is opposite the largest angle. You can compare the lengths of the sides to find the largest.

Front

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

Back

In a triangle, the larger the angle, the longer the side opposite that angle.

Front

What is an altitude in a triangle?

Back

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

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = 1/2 * base * height.

Front

What is the significance of midsegments in triangles?

Back

Midsegments help in determining the properties of triangles, such as similarity and proportionality of sides.

Front

How do you find the length of a midsegment?

Back

The length of a midsegment is half the length of the side it is parallel to.

Front

What is the sum of the interior angles in a triangle?

Back

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