In this page 10th grade geometry worksheet2 we are going to see some practice questions. You can try the below problems on your own. If you find it difficult to do any problems you can just click the solution link to get detailed solution.
(9) In a triangle ABC,AD is the internal bisector of angle A, meeting BC at D.
(i) If BD = 2
cm, AB = 5 cm, DC =3 cm find AC. solution
(ii) If AB = 5.6 cm, AC = 6 cm and DC = 3 cm find BC. solution
(iii) If AB =
x, AC = x – 2 cm, BD = x + 2 cm and DC = x – 1 find the value of x
(10) Check whether AD is the bisector of angle A of the triangle ABC in each of the following.
(i) AB = 4 cm, AC = 6 cm, BD = 1.6 cm and CD = 2.4 cm solution
(ii) AB = 6 cm, AC = 8 cm, BD = 1.5 cm and CD = 3 cm solution
(11) In a triangle MNO, MP is the external bisector of angle M meeting NO produced at P. IF MN = 10 cm, MO = 6 cm, NO - 12 cm, then find OP. Solution
(12) In a quadrilateral ABCD, the bisectors of ∠B and ∠D intersect on AC at E. Prove that (AB/BC) = (AD/DC). Solution
(13) The internal bisector of ∠A of triangle ABC meets BC at D and the external bisector of ∠A meets BC produced at E. Prove that (BD/BE) = (CD/CE). Solution
(14) ABCD is a quadrilateral with AB = AD. If AE and AF are internal bisectors of ∠BAC and ∠DAC respectively,then prove that the sides EF and BD are parallel.

We also provide math videos:
Math Videos are major sources for the students to learn math for their convenience. If a student goes to attend a particular class on math, he has to concentrate completely and take notes of what is taught in the class. And the student can not record each and everything explained by the tutor in the class. The student would be taking notes of only some important points. When the student is out of concentration for few seconds, the tutor may say some important points. And the student may not have chance to ask the tutor to repeat that. In this situation, if the student wants to recap what has been taught or explained about a particular thing in the class, he may have confusion
