## Important Questions for Class 10 Maths Triangles

1.If âˆ†ABC ~ âˆ†PQR, perimeter of âˆ†ABC = 32 cm, perimeter of âˆ†PQR = 48 cm and PR = 6 cm, then find the length of AC.

2. âˆ†ABC ~ âˆ†DEF. If AB = 4 cm, BC = 3.5 cm, CA = 2.5 cm and DF = 7.5 cm, find the perimeter of âˆ†DEF.

3. If âˆ†ABC ~ âˆ†RPQ, AB = 3 cm, BC = 5 cm, AC = 6 cm, RP = 6 cm and PQ = 10cm, then find QR.

4.In âˆ†DEW, AB || EW. If AD = 4 cm, DE = 12 cm and DW = 24 cm, then find the value of DB

5. In âˆ†ABC, DE || BC, find the value of x.

6. In the given figure, if DE || BC, AE = 8 cm, EC = 2 cm and BC = 6 cm, then find DE.

7. In the given figure, XY || QR, PQ/XQ=7/3 and PR = 6.3 cm, find YR.

8. In the figure, EF || AC, BC = 10 cm, AB = 13 cm and EC = 2 cm, find AF.

9. X and Y are points on the sides AB and AC respectively of a triangle ABC such that AX/AB=1/4, AY = 2 cm and YC = 6 cm. Find whether XY || BC or not.

10. In the given figure, âˆ A = 90Â°, AD âŠ¥ BC. If BD = 2 cm and CD = 8 cm, find AD.

11. In the figure ABC and DBC are two right triangles. Prove that AP Ã— PC = BP Ã— PD.

12. In the given figure, CD || LA and DE || AC. Find the length of CL if BE = 4 cm and EC = 2 cm.

13. If a line segment intersects sides AB and AC of a âˆ†ABC at D and E respectively and is parallel to BC, prove that AD/AB=AE/AC.

14. âˆ†ABC ~ âˆ†PQR. AD is the median to BC and PM is the median to QR. Prove that AB/PQ=AD/PM.

15. **Assertion (A):** If âˆ†ABC and âˆ†PQR are congruent triangles, then they are also similar triangles.**Reason (R):** All congruent triangles are similar but the similar triangles need not be congruent.

16**. Assertion (A): **In the âˆ†ABC, AB = 24 cm, BC = 10 cm and AC = 26 cm, then âˆ†ABC is a right angle triangle.**Reason (R): **If in two triangles, their corresponding angles are equal, then the triangles are similar
