Practice Questions

Question 1

In the diagram below, lines $L_1$ and $L_2$ are parallel, and they are intersected by a transversal line $T$. If the measure of $\angle A = (3x + 10)^{\circ}$ and the measure of $\angle B = (2x + 30)^{\circ}$, where $\angle A$ and $\angle B$ are consecutive interior angles, what is the value of $x$?

Question 2

Given two parallel lines cut by a transversal, if an exterior angle on one side of the transversal measures $130^{\circ}$, what is the measure of the alternate interior angle?

Question 3

In a triangle, the measures of the angles are in the ratio $2:3:4. What is the measure of the largest angle?

Question 4

Lines $m$ and $n$ are parallel. If $\angle 1$ and $\angle 2$ are corresponding angles, and $\angle 1 = (5x - 15)^{\circ}$ and $\angle 2 = (3x + 25)^{\circ}$, what is the measure of $\angle 1$?

Question 5

If two lines intersect such that one of the angles formed is a right angle, what can be concluded about the two lines?
