Activity 1.1 Composing Polygons Using Triangles

YOUR TASK

Form or compose polygons such as triangles, squares, and parallelograms using triangles, describe your process, and justify why you think you have composed the required polygons.

A.1 COMPOSE a triangle

Use two or more triangles to compose at least one bigger triangle in the applet below. Type the name of the new triangle.

You can drag or rotate these triangles to compose new figures. Use the pink vertex to drag the triangle and the blue vertex to rotate it.

Write your step-by-step process to form a new triangle from the given triangles. Write it in a way that others can follow the process on their own. Isulat kung ano ang iyong mga naging hakbang para makagawa ng bagong triangle mula sa mga nakalaan. Isulat ito para madaling masundan ng iba.

A.3 JUSTIFY

Provide reasons why you think the polygon you composed above is a triangle. Ipaliwanag kung paano ka nakasigurado na iyong na-compose ay isa ngang triangle.

B.1 COMPOSE a square
