Question

Ex 1.3 question 6 of 12 why it is onto

EF is parallel to the tangent at A, point on the circle and Angle ABC= 57 ,Angle ACB = 55, the measure of Angle AFE??

Triangle ABC is circumscribed touching the circle at P,Q,R.if AP= 4 cm, BP= 6 cm, AC = 12 cm, BC= x cm. Then x=? 

BoC is a diameter of a circle with centre O. If AB and CD are two  chord such that AB  parellel to CD. If AB = 10 cm, then CD=?

a triangle and parallelogram have same base and same area if the side of triangle are 26cm,28cm and 30cm and the parallelogram stands on the base 28cm then find the height of the parallelogram

1. In triangle ABC AD perpendicular to Bc such that ADsqure = Bc.  CD prove that ABC is a right angle triangle 
   

 can we get some question sample papers of class 4 . I want the papers of science.

thanks
