    Honeylyn SM Araneta
    The document describes a lesson on angles and types of quadrilaterals. It defines acute, right, and obtuse angles using models. It also defines the properties of triangles and quadrilaterals using objects. The lesson then reviews angles and introduces different types of quadrilaterals - square, rectangle, rhombus, parallelogram, and trapezoid - describing their defining attributes. Students are given activities to identify properties of quadrilaterals as correct or incorrect and identify shapes in diagrams as different types of triangles or quadrilaterals.

    1. Describe and illustrate different angles


    ( acute, right, obtuse ) using models.
    M4GE - IIIb - 14.
    2. Describe the attributes / properties of
    triangles and quadrilaterals using
    concrete objects or models. M4GE - IIIb -

    Review :

    In our previous lesson we had learned


    about ANGLES.
    Angles are formed when two rays meet at
    one common endpoint.
    The kinds of angles are acute, right,
    obtuse, straight
    Review : Choose the letter of the correct
    answer.
    1. Which of the following tells true
    statement?
    a. Perpendicular lines forms a square
    cornes.
    b. Parallel lines meet at a point.
    c. Intersecting lines never meet at one
    point
    Review : Choose the letter of the correct
    answer.
    2. Which of the following are parallel
    lines?
