image of a triangle

Find the coordinates of A′, the image of vertex A, if triangle ABC is rotated 90° clockwise around the origin. => (- 2, 3) or (2, 3) or (- 3, - 2) or (- 3, 2)..

Triangle - A three sided closed figure is called a triangle. Here side means a line segment. ABC is a triangle. BC, CA, AB are its sides. They can be denoted by small letters a, b and c. The capital letters A, B and C denote the vertices of the triangle..

A(- 2, 1), B(- 4, -1) and C(2, - 3) are the vertices of a triangle. Find the coordinates of the vertices of ΔA'B'C', the image of ΔABC under the translation <4, 2>. => (6, 3), (8, 3) and (2, 5) or (- 6, - 1), (- 8, - 3) and (- 2, - 5) or (2, 3), (0, 1) and (6, ..

The coordinates of the vertices of triangle PQR are P (3, 4), Q (3,1) and R (1, 1). Which of the graphs best suits for the image of PQR after counterclockwise rotation of 90 o about the origin? => Graph 2 or Graph 4 or Graph 3 or Graph 1..

Congruent Triangles - When two triangles have (i) the same shape, and (ii) the same size, then they are said to be congruent triangles. Symbol for congruency is Draw with AB = 4 cm, AC = 5 cm, and . Also with DE = 4 cm, DF = 5 cm and Draw these triangles on a..

Introduction - A triangle is a geometrical figure formed by three lines, which intersect each other and which are not all concurrent. A triangle ABC has six parts namely three angles and their sides namely AB, BC, CA. Triangles can be classified either on the basis of ..

Theorem: - In any triangle ABC, prove that the area of a triangle ABC is given ..

We have already learnt in the previous class that the area of triangle whose vertices are (x 1 , y 1 ), (x 2 , y 2 ), (x 3 , y 3 ) is given by Hence area of a triangle having vertices at (x 1 , y 1 ), (x 2 , y 2 ) and (x 3 , y 3 ) is given by..

Area of a triangle - If the coordinates of the vertices of the D ABC are A(x 1 ,y 1 ), B(x 2 ,y 2 ) and C(x 3 ,y 3 ), then the area of triangle is given ..
