Ghlj and gstu are both parallelograms. why is ∠l ≅ ∠t?

When the opposite sides of a quadrilateral are parallel to each other then the figure is called a parallelogram. Thus,  ∠L ≅ ∠T

Given parallelograms, GHLJ and GSTU such the parallelogram GSTU is inscribed inside parallelogram GHLJ with angle G coinciding on the two parallelograms.

Recall that a property of a parallelogram states that the opposite angles of a parallelogram are equal.

Thus, angle G is similar to angle T and angle L.

Therefore, ∠L ≅ ∠T

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
