Teacher's ActivityPupils' Activity
Hello class! Hello ma'am!
Identify the following geometric figures
1 ) pointв—Џ
2 . line portion в—Џ в—Џ
4. seite an seite lines
five. intersecting lines
6. verticle with respect lines
six. right angle
8. serious angle
being unfaithful. obtuse viewpoint
What is the figure under? A physique of a man
What particular geometricpolygons
determine is used to symbolize
the body parts?
What polygons can you seerhombus, rectangle,
from this picture? trapezoid, triangle
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
Farrenheit. Tell something about the polygons based from your data.
G. Discuss you observations among the group.
So what do we call up 3-sided
What are the types ofequilateral, isosceles,
polygons in accordance to sides? and scalene
Who can bring and identify
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,
kinds of quadrilaterals? rhombus, parallelogram
That can draw and describe(pupils answer)
each type of quadrilateral?
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
Name every single triangle and write when it is equilateral, isosceles or scalene. 1 . installment payments on your
10cm 5. 4cm 4cm
Identity each triangle and write if it is serious, right or perhaps obtuse.
7. twenty two
Encircle the right name to spot each quadrilateral
