We know that a right angle measures 90 degrees and a straight angle measures 180 degrees.
Usually we would use a protractor to measure angles but if we know the angle is a right or straight angle then we can use a calculation to work out the angle size. Sometimes these angles can be split to create smaller angles. Here are straight angles split into smaller angles:
