geometry activities for middle school students

Complete the following table by measuring the interior and exterior angles of the figure given above using a protractor. Study the table carefully and identify the relation between exterior and interior opposite angle..

Draw a scalene triangle, an acute angled triangle, an obtuse angled triangle, an equilateral triangle and a right angled triangle. Measure the angles in all the figure. Enter the measure in the table given. What do you observe? What do you conclude with respect to the sum of the magnitudes of all ..

Draw a triangle ABC. Mark the mid-points of BC, AC and AB as D, E and F respectively. Join AD, BE, CF. AD, BE and CF are the three medians of D ABC. They pass through (or meet) at the same point (or common point). G is the point of concurrence of the medians. It is called as centroi..

Distance between parallel lines: Draw two lines along the two edges of a scale. You get parallel lines (l and m). Let l || m. ..

Draw parallel line segments and parallel rays as shown below. The distance between parallel lines is the same at every poi..

Mark two distinct points A and B on the plane of your note book. Can you draw a line passing through A and B? By experience we find that we can draw only one line through two distinct points A and B. Hence "Given any two distinct points in a plane, there exists one and only line containing them"..

a) Given an equation, to find the corresponding locus. b) Given a locus under some geometrical condition to determine the corresponding equation. The following properties of the curve will be very helpful in determining the full form of locus equation. i) Intercept: The intercept of a curve are th..

A triangle is a plane closed geometric figure formed by three line segments joining three non-collinear points. In our previous classes, we have found the sum of three angles of a triangle. An activity is suggested here to find the sum of three angles of a triangl..

Angle sum property - A triangle is a plane closed geometric figure formed by three line segments joining three non-collinear points. In our previous classes, we have found the sum of three angles of a triangle. An activity is suggested here to find the sum of three angles of a triangl..
