Geometry Basics Solver

About Geometry Basics

Geometry rewards students who draw the figure neatly before writing a single calculation. This topic covers lines and angles (complementary, supplementary, vertically opposite), triangle properties (angle sum, exterior angle, isosceles), quadrilaterals (parallelogram, rhombus, trapezium), circles (chord, tangent, basic theorems), and the simple theorems Class 7–8 students are expected to apply. The 11 solved examples each include a clean diagram, the 'given' and 'to find' lines, and the standard step-marked layout that examiners look for in CBSE and ICSE answer booklets.

What this calculator does

• Step-by-step working. Every intermediate line is shown, in the layout examiners reward in CBSE / ICSE and university scripts.
• Graphs where they help. Functions and equations are plotted so you can see the result rather than just read it.
• Verification. The answer is substituted back into the original problem so you know the working is consistent.
