Subject Experts Solutions for Chapter: Understanding Quadrilaterals, Exercise 5: SUMMATIVE ASSESSMENT

In the given figure, the value of $x$ is

In a square $\mathrm{ABCD}$, if the diagonals bisect at $\mathrm{O}$. Then $∆\mathrm{AOB}$ is

For which of the following quadrilaterals, diagonals are perpendicular to each other?

In the given figure, $\mathrm{ABCD}$ is a rhombus.$AEC$ and $BED$ are two straight lines.

Find the value of $(p+q+r+s+t)$.

A farmer’s grass field is in the form of a parallelogram $PQRS$. One of its animals a cow broke open and grazed in the entire field. The farmer beat it and tied it at one corner $Q$ and reduced its grazing area. If $\angle PQS=36°$, then find all remaining angles of his grass field. What values does the farmer lack?

A farmer’s grass field is in the form of a parallelogram $PQRS$. One of its animals a cow broke open and grazed in the entire field. The farmer beat it and tied it at one corner $Q$ and reduced its grazing area. If $\angle PQS=36°$, then find $\angle PQS, \angle RQS$ and $\angle RSQ$.
