Circles Practice Question Set | Geometry Class 10

In this video, I have solved the following questions. 1) A quadrilateral ABCD is drawn to circumscribe a circle. Prove that AB + CD = AD + BC. 2) In the given figure, a circle is inscribed in a quadrilateral ABCD touching its sides AB, BC, CD and AD at P, Q, R and S respectively. If the radius DA of the circle is 10 cm, BC = 38 cm, PB = 27 cm and AD ⊥ CD, then calculate the length of CD. 3) In the given figure, quad. ABCD is circumscribed touching the circle at P, Q, R and S. If AP = 5 cm, BC= 7 cm and CS = 3 cm. Then, the length of AB =-----. 4) Prove that the parallelogram circumscribing a circle is a rhombus. #cbse #exam #education #educational #class10 #educationalvideo #educationalcontent #maths #mathematics #exampreparation #math #mathproblems #maths #class10 #Class10Maths#cbse #Circles #TangentTheorem #TangentsToACircle #CircleTheorems #Geometry #Maths #MathsClass10 #Class10Maths #NCERTMaths #BoardExamPreparation #MathsProofs #LearnGeometry #MathsConcepts #ExamOriented #education #icse #grade10 #cirlce
