WebUnit six is about using the coordinate plane to prove the similarity and congruence relationships from previous units analytically. Students use coordinates to verify geometric relationships by finding slope and distance of a line to support their proof. If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio and hence the two triangles are similar. Let ∆ABC and ∆PQR are two triangles. Then as per the theorem, AB/PQ = BC/QR = AC/PR (If ∠A = ∠P, ∠B = ∠Q and ∠C = ∠R) And ∆ABC ~ ∆PQR See more In any triangle, the sum of the three interior angles is 180°. Suppose XYZ are three sides of a Triangle, then as per this theorem; ∠X + ∠Y + … See more If a side of the triangle is produced, the exterior angle so formed is equal to the sum of corresponding interior opposite angles. For a triangle, XYZ, ∠1, ∠2, and ∠3 are interior … See more If a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side. Suppose XYZ is a triangle and a line L M divides the two sides of triangle XY and XZ in the same ratio, such that; XL/LY = X M/M Z See more The base angles of an isosceles triangle are congruent. Suppose a triangle XYZ is an isosceles triangle, such that; XY = XZ [Two sides of the triangle are equal] Hence, ∠Y = ∠Z … See more
