GEOMETRY CALCULATORS

This is the Teletext-Tools geometry calculators hub.

It links to area, perimeter, volume, surface area, circle and triangle tools.

It also links to Pythagoras, trigonometry and scale factor calculators.

Use Page 1 as the fast menu for geometry calculator pages.

Start on Page 1 and choose the geometry calculator you need.

Use 631 for area, 632 for perimeter and 633 for volume.

Use 634 for surface area, 635 for circles and 636 for triangles.

Use PREV and NEXT to move through help pages without scrolling.

Use area to find flat space inside a 2D shape.

Use perimeter to find the total outside length of a shape.

Use volume to find space inside a 3D solid.

Use surface area to find the total area of the outside faces.

Use the triangle solver for side and angle questions.

Use Pythagoras for right-angled triangle side lengths.

Use trigonometry for SOHCAHTOA questions.

Use scale factor for similar shapes, enlargements and scale drawings.

Students use this hub for GCSE geometry homework and revision.

Teachers use it to jump quickly to shape formula calculators.

Tutors use it for area, perimeter, volume and triangle examples.

Parents can use it to support school geometry questions.

Calculate shape measurements for homework and exam practice.

Check formulas for 2D shapes, 3D solids and circles.

Use triangle tools for right-angle geometry and trigonometry.

Use scale tools for similar shapes, drawings and enlargements.

The menu keeps geometry calculators grouped in one place.

Each linked page is designed for phone, tablet and laptop screens.

The internal pages split help text into readable panels.

The PREV and NEXT controls stay visible on every page.

Geometry connects with number, ratio, percentages and algebra tools.

Which tool finds flat space? Use the area calculator.

Which tool finds outside length? Use the perimeter calculator.

Which tool is for 3D solids? Use volume or surface area.

Which tool is for right triangles? Use Pythagoras or trigonometry.
