Theorem 7.6 : If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater)

Text Solution

Verified by Experts


Let us assume a triangle `ABC` such that the sides are as `AB > AC`.
Now, take a point `P` on line `AB` such that `AP = AC`. Join the two points `C` and `P` to set `CP`. Let us assume angle `APC` is `x` and angle `BCP` is `y`.
. We know that `AP = AC`.
If two sides are equal in a triangle, then the angles opposite to the sides are equal. Applying this condition to the triangle `APC`, we get the angle `APC` and angle `ACP`, all equal. As angle `APC` is `x`,
we get the angle `ACP` also `x`.
Mathematically, we write these steps as follows:
`/_ACP=/_APC`
