A trapezoid is a quadrilateral with one pair of parallel lines.
BasesThe two parallel lines are called the bases The LegsThe two non parallel lines are the legs. . 
Adjacent Angles of TrapezoidThe angles on the same side of a leg are called adjacent angles such as  NML and MLO are supplementary. For the same reason, MNO and NOL are supplementary. 
Use adjacent angles theorem to calculate m
MLO.
What is wrong with trapezoid LMNO pictured below? (Explain why LMNO cannot be a trapezoid based on the information provided)
Answer
Midsegment of Trapezoid The midsegment of a trepzoid is
Use the midsegment theorem to determine the length of midsegment ON.
length of midsegment= (6+4)/2 = 5 
Quick REVIEW of Midpoint. 
The midpoint of the red segment pictured on the left is the point (A, 2b). The most important thing to remember is that a midpoint bisects a line (cuts a line into two equal halves). Show Midpoint The midsegment of a trapezoid is the segment that joins the midpoints of the nonparallel sides of a trapezoid. In the trapezoid below, the midpoints of the non-parallel sides are points S and V. The midsegment is the red line segment from S to V. 
What is the length of midsegment SV in the trapezoid below?
answer
Length of top base = 17-8 = 9
Length of bottom base= 20-0 =20 Sum of bases = 9 + 20 = 29 Divide sum of bases by 2 = ½(29) = 14.5 Therefore, the midsegment SV is 14.5 in length.
Is the reg segment below a midsegment?
It is not a true midsegment because its length does not equal half the sum of the lengths of the bases. |
