Figures having same shape and size are called …… figures.

Two squares are congruent if they have same

If $\mathrm{△}PQR\backslash triangle\; PQR$ $\cong \backslash cong$ $\mathrm{△}ABC\backslash triangle\; ABC$ then $\mathrm{\angle }R\backslash angle\; R$ = ........

Any two circles are

In the figure $\mathrm{△}ABC\backslash triangle\; ABC$ $\cong \backslash cong$ $\mathrm{△}CDA\backslash triangle\; CDA$ by

In the figure PQ = RS; bisect at ‘O’ then $\mathrm{△}POR\cong \mathrm{△}QOS\backslash triangle\; POR\backslash cong\; \backslash triangle\; QOS$ by

$\overline{XY}\backslash overline\{XY\}$ is the perpendicular bisector of $\overline{PQ}\backslash overline\{PQ\}$ Then $\mathrm{△}POX\cong \mathrm{△}QOX\backslash triangle\; POX\backslash cong\backslash triangle\; QOX$ by

If in $\mathrm{△}DEF;\backslash triangle\; DEF;$ DF is the longest side then the greatest angle is

If three angles of a triangle are equal to three angles of another triangle then they are

 A triangle in which two sides are equal is called:
