Triangle ABC and PQR are said to be congruent ( ABC ≅ PQR), if length AB = PR, AC = QP, and BC = QR. . 1 … The two triangles are 120 o. Question 100. If two angles of a triangle are 60° each, then the triangle is (a) Isosceles but not equilateral (b) Scalene (c) Equilateral (d) Right-angled Solution:-(c) Equilateral. Algebra Quadratic Equations and Functions Linear, Exponential, and Quadratic Models The perimeter of the rectangle whose length is 60 cm and a diagonal is 61 cm is Hence Option B is the answer. If the medians RS and QR intersect at right angle, then prove that (PQ/QR) 2 = 5/2. and by the similar triangles property, the corresponding angles are equal. TCS Question Solution - If triangle PQR , if PQ=6 c m, PR = 8 c m, QS=3 c m and PS is t he bisector of . Answer 15. If R Q, then PQPR. 60 o. Construct an isosceles triangle PQR in which PQ = PR, base QR = 5.6 centimetres, angle PQR = 75 degrees using a ruler and a pair of compasses. Name this copy as ∆A 4 B 4 C 4. So the lengths are x, x+1, & x+2 And tangent segments from an exterior points are equal. What happens when Copper reacts with Silver nitrate solution? Jun 25, 2016 . In ∆PQR, ∠R> ∠Q ∴ PQ > PR (b) Question 16. Since PQ is a straight line passing through centre, then PQ is a diameter. The following figure shows a triangle PQR in which XY is parallel to QR. Maths .
The radius of the in circle of triangle PQR is
