According to the graph, triangle JKL and triangle MNO are isosceles, where JL and MN are their respective bases.
It is important to know that the base angles of an isosceles triangle are equal. Basically, angle J is congruent to angle L, angle M is congruent to angle N.
Additionally, angle K is greater than angle O because its opposite side is greater.
Hence, the right answers are A, B, and D.
