Max Maths, Year 5, Try it, Angles on a straight line

In a mathematics exercise designed for Year 5 students, the focus is on understanding and calculating angles on a straight line. The key concept being taught is that the sum of angles on a straight line adds up to 180 degrees. The exercise, titled "Let's Try It," presents a series of problems that require students to apply this principle to find missing angles when given one or more angles on a straight line.

The first problem presents a straight line with points I, F, G, and H marked on it, forming angles along the line. One of the angles, marked as 30 degrees at point G, is given, and students are tasked with finding the angle at point IGH by subtracting the known angle from the total sum of 180 degrees. The second problem involves a different straight line with points R, S, T marked, and an angle of 55 degrees given at point S. Students must again use the total sum of angles on a straight line to find the unknown angle marked as 'q'. These exercises encourage students to use subtraction and their knowledge of the properties of angles on a straight line to solve for the unknown angles.
