Triangles ratio
WebAn equilateral triangle with side lengths of 2 cm can be used to find exact values for the trigonometric ratios of 30° and 60°. The equilateral triangle can be split into two right … WebArea and Perimeter Relations. If two triangles are congruent, then they will have the same area and perimeter. If two triangles are similar in the ratio R R, then the ratio of their perimeter would be R R and the ratio of their area would be R^2 R2. \frac {R} {dr} drR \frac {r} {R}d Rr d \frac {R} {d}r dRr \frac {R} {r}d rRd.
