Draw any obtuse ΔOBT. Use the SSS method to construct a triangle congruent to ΔOBT.

Short Answer

Expert verified

By SSScongruency ΔOBT≅ΔPQR.

Step by step solution

01

Step 1. Given information.

An obtuse ΔOBT is given.

02

Step 2. Draw the obtuse triangle.

ObtuseΔOBT is drawn below.

Here, ΔOBT is an obtuse triangle as ∠OBT>90°.

03

Step 3. Concept used.

According to SSS congruence criteria,

if all the sides of one triangle are congruent to the corresponding sides of other triangle,

then the two triangles are said to be congruent.

04

Step 4. Construct the congruent triangle.

Construct ΔPQRsuch that PQ≅OB, PR≅OT, QR≅BT.

So,

ΔOBT≅ΔPQR (by SSScongruence criteria)

Therefore,by SSScongruency ΔOBT≅ΔPQR.
