Embibe Experts Solutions for Chapter: Geometry, Exercise 2: Lines and angles

In the given fig, find the value of $\angle QPB$.

AB and CD are parallel line segments of length $8 cm$ and  $7 cm$, respectively. If AD and BC intersect at O and $AO=16 cm$, then OD is equal to:

In the figure given below, $p, q, r$ are parallel lines; $l$ and $m$ are two transversals.

Consider the following:
1. $AB:AC=DE:DF$
2. $AB\times EF=BC\times DE$
Which of the above is/are correct?

If the magnitude of an angle is $325°$, then the angle is __________

If $X$ is a point on the line $AB$ and $Z$ and $Y$ are points outside such that $\angle AXY=45°$ and $\angle YXZ=150°$, then $\angle AXZ$ is equal to:

If parallel lines $l, m, n$ and transversal line $t_1$ and $t_2$ cut each other at the points $A, B, C$ and $P, Q, R$ as shown in the figure, then

If two straight lines $AB$ and $XY$ intersect each other at the point $O$ and $\angle AOX=3\angle XOB$, then the four angles formed at $O$ are:

In the given diagram, $CE$ is parallel to $AD$ and the measures of two angles at $B$ and $C$ are given. Then the angle $DAB$ is equal to:
