In the isosceles trapezoid above,. Explanation : To find the measure of angle DAC, we must know that the interior angles of all triangles sum up to degrees.
Given the following isosceles triangle:. Similarly, the two bottom angles are equal to each other as well. Copyright Notice. Fion Certified Tutor. Diagram 2. Adjacent Angles of Trapezoid.
Practice Problems. Measure of angle. Show Answer. Midsegment of Trapezoid. The midsegment of a trapezoid is: parallel to both bases measure of its length equals the average of the length of the bases. Midsegment's Length. Quick review of Midpoint The most important thing to remember is that a midpoint bisects a line cuts a line into two equal halves. Show Midpoint. This is actually true of any quadrilateral. Let lower case letters a, b, c and d represent the angles of trapezoid ABCD. The corresponding pairs of base angles, such as A and B, or C and D, are supplementary add up to degrees.
