Question
**Classify the Triangle by its Angles and by its Sides** 1. **Triangle 1** - Angles: 68°, 22° - Angle type: These angles add up to 90°, which, together with the third angle, makes it an acute triangle (all angles less than 90°). - Side type: Information about sides is not given, but with the angles available, it could be assumed it may not be equilateral or isosceles. 2. **Triangle 2** - Each angle is 19°. - This is not possible for standard triangles, as the sum of angles in a triangle must be 180°. There seems to be a misunderstanding or error if this is meant to be a full triangle. 3. **Triangle 3** - Angles: Two angles are each 60°. - Angle type: This is an equilateral triangle, as all angles are equal (60° each). - Side type: Additionally, because all angles are 60°, all sides are equal, making it equilateral. Note: Each diagram requires the angles to sum to 180° for valid triangle configuration and classification.
