Question

In the adjoining figure BP 1 AC, CQ 1 AB, A-P-C, A-Q-B, then prove that AAPB and AAQC are
similar.​

Answer 1

Step-by-step explanation:

1. proff: 2. SAS test for similarity of triangles: For a given correspondence, if two pairs of corresponding sides are in the same proportion and the angle between them is congruent, then the two triangles are similar. In the given figure, if AB/PQ = BC/QR, and ∠B ≅∠Q, then ∆ABC ~ ∆PQR 3. SSS test for similarity of triangles: For a given correspondence, if three sides of one triangle are in proportion with the corresponding three sides of the another triangle, then the two triangles are similar. In the given figure, of AB/PQ = BC = QR = AC/PR, then ∆ABC ~ ∆PQR Properties of similar triangles: 1. Reflexivity: ∆ABC ~ ∆ABC 2. Symmetry : If ∆ABC ~ ∆DEF, then ∆DEF ~ ∆ABC.

3. Transitivity: If ∆ABC ~ ∆DEF and ∆DEF ~ ∆GHI, then ∆ABC ~ ∆GHI.Read more on Sarthaks.com - https://www.sarthaks.com/849902/in-the-adjoining-figure-bp-ac-cq-ab-a-p-c-a-q-b-then-prove-that-apb-and-aqc-are-similar
