8 questions with a History theme plus a full answer key. Perfect for Grade 4 Math.
⬇ Download WorksheetStudents will identify, measure, and calculate angles including right, acute, obtuse, and straight angles using addition and subtraction of angle measures.
Before Q6, pause and ask students: 'Can two acute angles add up to form an obtuse angle?' Let pairs predict using Q5's corner-stone work, then verify with protractors — this bridges directly to Q7's unknown-angle calculation on the worksheet.
- Maya enters an ancient temple. She spots a special object — a carved stone door. The door swings open 90 degrees. Is this angle right, acute, or obtuse? Write the angle type and the number of degrees.
- Maya shines her torch at a unique item — a golden arrow on the wall. The arrow points at an angle of 35 degrees. Is 35° acute or obtuse? An acute angle is less than 90°. Write your answer with the number.
- Maya finds a rare find — an old stone compass on the floor. One compass arm points at 65°. The other arm points at 47°. Maya adds both angles together. What is the total angle between the two arms?
