$(xi) It two medians of a triangle are congruent then the triangle will be ......(a) isosceles(b) equilateral(c) right angled(d) acute angled$

$4. Construct the following \Delta \mathrm{s} \mathrm{XYZ} . Draw their three medians and show that they. are concurrent.(ii) \mathrm{m} \overline{\mathrm{XY}}=4.5 \mathrm{~cm} \mathrm{mYZ}=3.4 \mathrm{~cm} and \mathrm{mZX}=5.6 \mathrm{~cm}$

$4. Construct a right-angled triangle equal in area to a given square.$

$4. Construct the following \Delta \mathrm{s} \mathrm{XYZ} . Draw their three medians and show that they. are concurrent.(iii) \mathrm{m} \overline{\mathrm{ZX}}=4.3 \mathrm{~cm}$

$5. (Ambiguous Case) Construct a \triangle \mathrm{ABC} in which(ii) \mathrm{m} \overline{\mathrm{BC}}=2.5 \mathrm{~cm} \mathrm{~m} \overline{\mathrm{AB}}=5.0 \mathrm{~cm} \mathrm{~m} \angle \mathrm{A}=30^{\circ} (one \Delta )$

$1. Construct a \Delta with sides 4 \mathrm{~cm} 5 \mathrm{~cm} and 6 \mathrm{~cm} and construct a rectangle having its area equal to that of the \Delta . Measure its diagonals. Are they equal?$
