Your class will be broken into 4 teams

Each group will be given envelopes made up of polygons and activity cards. They will the actual instructions which were written inside the activity greeting cards.

Activity credit card:

B. Individual the 3-sided polygons as a result of the 4-sided polygons. C. Number the polygons individually as you, 2, 3, etc .

Deb. Measure the length of the sides of the numbered polygons. E. Record the data

G. Discuss you observations among the group.

Deb. Discussion

So what do we call up 3-sided

polygons? triangles

What are the types ofequilateral, isosceles,

polygons in accordance to sides? and scalene

Who can bring and identify

each triangular?

What are the kinds of anglesobtuse, right and

according to angles? serious triangle

So what do we phone 4-sided

Exactly what the differentrectangle, square,

and trapezoid

That can draw and describe(pupils answer)

At the. Generalization

Three-sided polygons are called triangles

Kinds of triangle relating to attributes:

1 . Equilateral triangle- 3 sides will be equal or congruent

installment payments on your Isosceles triangle-two sides happen to be congruent

3. Scalene-no two sides will be congruent

Varieties of triangle in accordance to angles:

1 . Cruche triangle-one position is cruche

2 . Right triangle-one viewpoint is right

3. Acute triangle-three sides are typical acute

Four-sided polygons these are known as quadrilaterals

1 . Rectangle- offers two pairs of the same opposite attributes and it includes four right angles 2 . Square- all sides are the same and they have four proper angles

a few. Rhombus- has four equal sides

5. Parallelogram- has both pairs of opposite sides seite an seite

5. Trapezoid- it has one pair of opposite sides seite an seite

IV. Application
