Max Maths, Year 6, Learn together, Angles in a triangle (1)

In an engaging lesson from Max Maths for Year 6 students, the concept of angles within a triangle is explored through a hands-on activity. The lesson begins with a character named Jade, who draws and cuts out a triangle from a piece of paper. She proceeds to label each corner of the triangle with the letters 'a', 'b', and 'c'. Jade's next step is to cut the triangle into three separate pieces, each containing one of the labeled corners.

Following this, Jade cleverly repositions the three corners of the triangle so that they all meet at a single point. This visual demonstration leads to a fascinating revelation: when the angles at each corner are combined, they form a straight angle, which is always 180 degrees. This discovery is summarised by the equation x + y + z = 180°, where 'x', 'y', and 'z' represent the angles at each corner of the triangle. The lesson concludes with the key takeaway that the sum of the angles in any triangle will always add up to 180 degrees, a fundamental principle in the study of geometry.
