## Task 1 : Look the following figure by dragging.

identify the base, perpendicular and hypotenuse of right angle triangle and rename them as the part of pyramid.

## Look at the following figure and drag the point L and answer the following question

Write the points of the sides of base of pyramid where Fl defined as hypotenuse.

## You can alter the base and height of this square pyramid by dragging the 2 white points.

How would you describe the relationship between a square pyramid's LATERAL HEIGHT and its TRUE HEIGHT? To explore this resource in Augmented Reality, see the directions below the applet. Suppose each edge of the square base measures 10 cm. If this square pyramid's lateral height measures 13 cm, what would its true height be? What would the pyramid's lateral area be? What would its total surface area be?

## look at the following figure

## Watch the video to learn about the formula of volume of pyramid. and write it in copy.

## look at the following pyramid. and rotate C and Give the answer of the following question

When J at point F, then what is the relation between EDJ and EAJ? similarly when J at any other point except F on AD what is the relation between EDJ and EAJ?

## look at the following pyramids and Give the answer of following question.

Suppose each edge of the square base measures 10 cm. If this square pyramid's lateral height measures 13 cm, what would its true height be? What would the pyramid's lateral area be? What would its total surface area be? What would its volume be?
