First, locate each coordinate point on a graph, and join the points with straight lines.
An iscosceles trapezoid has equal base angles and equal left and right sides.
Sides:
SP and RQ
Apply Pythagorean theorem to find the lengths.
C^2 = a^2 + b^2
SP^2 =2^2 + 11^2
SP^2 = 4 + 121
SP ^2= 125
SP =√125
SP = 5
RQ^2 = 5^2 +10^2
RQ^2 = 25 + 100
RQ^2 = 125
RQ = √125
RQ = 5
Since both left and right sides are equal it is an isosceles trapezoid.
