IGCSE Grade 10 Maths Similar figures with side lengths and angle measures
|
Check whether the given figures are similar or not.
The scale factor between the two polygons is 3:5, which means that every side in the smaller polygon is 5/3 the length of the corresponding side in the larger polygon. This also means that every angle in the smaller polygon is 5/3 the measure of the corresponding angle in the larger polygon.
First, check whether the given figures are similar.
First, find out the length of the side AD.
Check the corresponding angle.
Since the spheres are similar, the ratio of the corresponding angle measures in the two spheres is constant.
Since the rectangles are similar, the ratio of their corresponding side lengths is constant.
Check the corresponding sides and their ratio.
Since the circles are similar, the ratio of their corresponding radii is constant.
Area of circle = \\(\\pi r^2\\)
Check whether the corresponding sides are proportional.
