smaller outside triangles. The outside triangles are isosceles triangles and all are equal to each other; furthermore‚ the tridecagon can be divided into thirteen isosceles triangles which are also equal to each other. Diamonds are formed from the combined outer and inner triangles. Thirteen diamonds are formed from the divided triskaidecagram and they are equal to each other. In finding the area of a thirteen-pointed star‚ the usual form is getting the area of one of the outer triangles then multiply

Describe the lesson or task you completed collaboratively in a paragraph consisting of five or more sentences. We went through a number of different triangles and justified them with the appropriate postulate or theorem. In addition‚ we chose‚ in groups of two (or three)‚ 2 triangles out of a series of choices and decided whether they were congruent or similar‚ and justified our statement with a postulate (Or theorem.) 2.

construction of those buildings. Understanding how to solve math problems becomes easier as one learns math terminology. Below is a list of many common math terms and their definitions. Acute angle – An angle which measures below 90°. Acute triangle – A triangle containing only acute angles. Additive inverse – The opposite of a number or its negative. A number plus its additive inverse equals 0. Adjacent angles – Angles with a common side and vertex. Angle – Created by two rays and containing an

and appliances‚ and even in fabrics and handicrafts. And one part of these shapes and angles is the angle bisector. Angle bisector is a ray that divides an angle into two congruent parts. It is also called the internal angle bisector. And the angle bisectors of a triangle intersect at a point called the incenter of triangle. This angle bisector is usually used or applied by the students in math particularly in the field of geometry. But unfortunately‚ there’s no device that can help the students
