theorem 6.6 proof of area of similar triangles
Question
What is the difference between radii of the same arc and arcs of equal radii？
Why we need to prove first that Triangle ACD and Triangle BCD both are homogeneous (uniform) while we already know that, for right triangle altitude and median both are same?
P is the midpoint of side AB of a parallelogram ABCD. A line through B parallel to PD meets DC at Q and AD produced at R. Prove that BC = 1/2 AR
For A = { 1 2 3 4}, find the relation in A for R = {(x,y) | x+y <5}, also write the range of R.
The perimetres of two similar triangles are 30cm and 20 cm respectively. If one side of the triangle is 12 cm. Determine the corresponding side of the second triangle
