Question

If each of the two equal angles of an isosceles triangle is 68${}^{\circ }$, find the third angle.

• A. SSS
• B. AAS
• C. ASS
• D. AAA

Answer 1

The correct option is A

SSS

180${}^{\circ }$ = 68${}^{\circ }$ + 68${}^{\circ }$ + $x$
$x$ = 180${}^{\circ }$ - 136${}^{\circ }$
$x$ = 44${}^{\circ }$
