Question

Identify the intersecting lines in the given figure.

  1. XY and WZ
  2. YZ and WX
  3. WX and XY;XY and YZ
  4. XZ and YW

hintHint:

We are given a figure with intersecting lines. We have to tell the lines that are intersecting. The lines that cross each other at some point are called as intersecting lines. One line can intersect another line only at one point.

The correct answer is: WX and XY;XY and YZ


    The given lines are WX ,XY and YZ.
    We have to find the intersecting lines.
    Intersecting lines cross each other and single point.
    From the figure, the line WX and XY meet each other at a point X.
    Similarly, the line XY and line YZ meet each other at a point Y.
    So, the lines that are intersecting lines are as follows:
    XY and WX
    XY and YZ
    The option which is “XY and WX; XY and YZ”, is the right option.

    For such questions, we should be careful about the intersecting points. The lines which cross each other at a point are intersecting lines. And no two lines can intersect each other at more than one point.

    Use the Vertical Angles Congruence Theorem to find the measure of each angle in the diagram at the right.

    For such questions, we should know properties of vertical angles. We should know the rules of algebra to solve the equations. The alternate way to solve the question will be using supplementary angles. When two angles intersect, the sum of adjacent angles is 180°.
