Today our Maths investigation was around triangles. Using the dot we had to make right-angle triangles. First, we had to make sure we all knew what that meant. Did you know a square and rectangle have 4 right angle corners? – That means the corners are 90°.
I will tell you how many we found after you tell me how many you find. Remember you can’t count a triangle of the size and shape twice. So be careful how you lay out your triangles, you can use this link to help you with your answer. Good Luck
