Which triangle is similar to δjkl? δjkm, δmkl, δkml, δljk.

Triangle is similar to the given triangle .

Step-by-step explanation:

Let us analyze the given options one by one.

is not similar to the triangle because it is not written in correct order. The way we write the triangle (order of vertices) is very important. Since angles K of both the triangles are not equal, therefore, order is messed up. If the order had been then this would have been correct.

is not similar to triangle because the corresponding angles are not equal. Again the order it not right. If the order had been , then this option would have been correct.

is similar to the given triangle because corresponding angles of both the triangles are equal.

is not similar to the given triangle because the corresponding angles of the two triangles are not equal.

120

Step-by-step explanation:

Lines a and b are parallel and cut by the same transversal, t. Since we know these lines are parallel, we can find the measure of angle 7 quite easily.

Angles 3 and 7 are corresponding angles, which means that the two angles are in the same relative position. Thus, they are equivalent.

Angle 3 = angle 7 = 120 degrees

The correct answer is 120.
