Answer:
Step-by-step explanation:
1). Since, two sides of the given triangle are equal in measure, triangle is an isosceles triangle.
2). By Pythagoras theorem,
(Hypotenuse)² = (leg 1)²+ (leg 2)²
(15.6)² = (14.4)² + (6)²
243.36 = 207.36 + 36
243.36 = 243.36
Therefore, given triangle is a right triangle.
3). Since, one angle is 123° which is greater than 90°, given triangle is an Obtuse triangle.
4). All interior angles and all sides of the triangle are equal in measure.
Therefore, given triangle is an equilateral triangle.
5). One angle of the triangle is a right angle.
Therefore, given triangle is a right triangle.
6). Since, all interior angles and sides of the given triangle are different in measure, it's a scalene triangle.
7). All angles and sides of the triangle are equal in measure,
Therefore, it's an equilateral triangle.
8). One angle of the triangle is measuring 106° which is greater than 90°.
Therefore, it's an obtuse angle.
