Important Questions for Class 10 Maths Triangles
1.If ∆ABC ~ ∆PQR, perimeter of ∆ABC = 32 cm, perimeter of ∆PQR = 48 cm and PR = 6 cm, then find the length of AC.
2. ∆ABC ~ ∆DEF. If AB = 4 cm, BC = 3.5 cm, CA = 2.5 cm and DF = 7.5 cm, find the perimeter of ∆DEF.
3. If ∆ABC ~ ∆RPQ, AB = 3 cm, BC = 5 cm, AC = 6 cm, RP = 6 cm and PQ = 10cm, then find QR.
4.In ∆DEW, AB || EW. If AD = 4 cm, DE = 12 cm and DW = 24 cm, then find the value of DB
5. In ∆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, ∠A = 90°, AD ⊥ 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 × PC = BP × 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 ∆ABC at D and E respectively and is parallel to BC, prove that AD/AB=AE/AC.
14. ∆ABC ~ ∆PQR. AD is the median to BC and PM is the median to QR. Prove that AB/PQ=AD/PM.
15. Assertion (A): If ∆ABC and ∆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 ∆ABC, AB = 24 cm, BC = 10 cm and AC = 26 cm, then ∆ABC is a right angle triangle.
Reason (R): If in two triangles, their corresponding angles are equal, then the triangles are similar
