60-Second Prep Please turn to your Problem Of The Week section! If you have your SWYK signed, please stand up and place it in your class basket.

Goals For Today To practice building specific triangles using geoboards

You will need: A geoboard A protractor AND/OR a ruler A pencil

Activity Please make a scalene triangle on your geoboard Then draw your triangle on the dot paper. Please use a ruler (or another straight edge) to connect the dots on your triangle Please save some room on your geoboard (and therefore, also on your dot paper) to put more triangles next to this scalene triangle.

Activity Now, make an isosceles triangle. Double-check that it is an isosceles triangle using a protractor and/or ruler. Finally, please draw it on your dot paper.

Activity Try making an equilateral triangle. If you think you have one, double-check it with a ruler and/or a protractor. Is it possible to make an equilateral triangle?

Please Flip your paper over  Please repeat the process, but this time make: A right triangle An obtuse triangle An acute triangle Please draw these triangles on your dot paper.
