The goal of this dynamic worksheet is to explore the postulates and theorems for congruent triangles. Try different combinations of sides and angles. Try ALL combinations for SSA to notice that this is a theorem for congruent triangles when the given an

Triangle Inequality

With the help of this activity, we have learnt that: 1.The sum of any two sides of a triangle is greater than its third side. 2.If a, b and c are lengths of the sides of a triangle then if a+b=c, all three Points will lie in a straight

Triangle Inequality

(View Complete Item Description)

Given three Lines segments of arbitrary lengths, determine if the segments can be joined end-to-end to form a triangle. Use the sample segments to investigate this situation. Use the check boxes to the right to focus your study.

Acute triangle

(View Complete Item Description)

An interactive applet and associated web page that demonstrate the three types of triangle: acute, obtuse and right. The applet shows a triangle that is initially acute (all angles less then 90 degrees) which the user can reshape by dragging any vertex. There is a message changes in real time while the triangle is being dragged that tells if the triangle is an acute, right or obtuse triangle and gives the reason why. By experimenting with the triangle student can develop an intuitive sense of the difference between these three classes of triangle. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Obtuse triangle

(View Complete Item Description)

An interactive applet and associated web page that demonstrate the three types of triangle: acute, obtuse and right. The applet shows a triangle that is initially obtuse (one angle greater than 90 degrees) which the user can reshape by dragging any vertex. There is a message changes in real time while the triangle is being dragged that tells if the triangle is an acute, right or obtuse triangle and gives the reason why. By experimenting with the triangle student can develop an intuitive sense of the difference between these three classes of triangle.
