tudeof the triangle ? Give reasons. 20. The sides of a right-angled triangle are 3, 4 and 5 inches. Ifa oint within the triangle be 1 inch from each of the sides contain-ing the right angle, how far is it from the hypotenuse ? 21. In a quadrilateral ABCD, AB = 2, BC = 3, and CD=1J inches.ABC = 35°,… … 1. Let the angle B of thetriangle ABC be 90\ Describesquares on the sides of ABC,as in the figure. Draw thelines AG, EF, CH parallel toBC; and the lines DK, EHparallel to AB. Then measurement (withdividers for lines, and bevelfor angles) will show that thetriangle AGD is in all respectsequal to the…
