Geometry SOL Review G.5 Triangles Sides and Angles

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

If two sides of a triangle are 10 and 5, what are the possible lengths for the third side?

Back

5 < x < 15.

Front

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

Back

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

Front

Given triangle UWV, if WV = 13, VU = 9, and UW = 15, which angle is the largest?

Back

Angle U is the largest angle.

Front

If one side of a triangle is 35, what are the possible lengths for the other two sides?

Back

The other two sides must be less than 70 and greater than 0.

Front

What is the range of possible lengths for the third side of a triangle with sides 12 and 7?

Back

5 < x < 19.

Front

How do you determine the smallest angle in a triangle?

Back

The smallest angle is opposite the shortest side.

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

If a triangle has angles of 30° and 60°, what is the measure of the third angle?

Back

The third angle measures 90°.

Front

What is an isosceles triangle?

Back

An isosceles triangle has at least two sides that are equal in length.
