Parts of a trapezoid
The parallel sides are called bases.
The other sides are called legs.basebaselegleg

ISOSCELES TRAPEZOIDA trapezoid with congruent legs is called an isosceles trapezoid.
What is true of the base angles? (2x + 10)o(-5x + 80)o(2x + 10)o= (-5x + 80)o= +5x +5x7x + 10 = 80 - 10 = - 10 7x = 70x = 10

Find the missing values.5x + y = 1415x + 7y = 58-3(5x + y = 14)15x + 7y = 58-15x - 3y = -4215x + 7y = 58 4y = 16 y = 45x + 4 = 14 - 4 = - 45x = 10 x = 2

Median of a TrapezoidThe median of a trapezoid is a segment that joins the midpoints of the legs.
The median of a trapezoid isIs parallel to the basesHas a length that is equal to average of the base lengths.1030x10 + 30 2 = x x = 20

Median of a TrapezoidFind the missing values.4x + 111x - 237(4x + 1) + ( 11x 2) 2= 37(4x + 1) + ( 11x 2) = 7415x 1 = 7415x = 75x = 5
