Answer:
Jonah formed a straight angle.
Step-by-step explanation:
- Acute angle is an angle less than 90 degrees.
- Obtuse angle is an angle greater than 90 but less than 180 degrees.
- Reflex angle is greater than 180
- Straight angle is equal to 180.
We know 3 angles of a triangle (no matter scalene, isosceles, right, equilateral triangle) sum up to 180 degrees. So, if Jonah were to cut of the 3 angles and put them points together, no overlap, he would eventually have a 180 degree angle, or a straight angle.
Jonah formed a straight angle.
