5.1 & 5.2

Front

What is the formula relating the midsegment of a triangle to its opposite side?

Back

2(midsegment) = opposite side.

Front

If the midsegment of a triangle is represented as 5x - 1, how do you find the value of x?

Back

Set up the equation: 2(5x - 1) = opposite side, then solve for x.

Front

What is the value of x if 2(5x - 1) = 10?

Back

x = 6.

Front

How do you find the length of a side of a triangle using the midsegment?

Back

Use the formula: Length of side = 2(midsegment).

Front

If the midsegment of a triangle is 8, what is the length of the opposite side?

Back

Length of opposite side = 2(8) = 16.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

If m∠JKM = 38°, what is the measure of the other angles if one is 90°?

Back

m∠JKM + 90° + m∠other = 180°, so m∠other = 52°.

Front

What is the value of x if 2x + 3 = 13?

Back

x = 5.

Front

How do you find the sum of two segments AD and CD if AD = 5 and CD = 14?

Back

AD + CD = 5 + 14 = 19.

Front

If AD + CD = 38 and AD = 5, what is CD?

Back

CD = 38 - 5 = 33.
