Question

1. name the triangle with the following characteristics. sides: 4 cm, 4 cm, 5.6 cm; angles: 45° and 45°. obtuse scalene triangle acute isosceles triangle right isosceles triangle equiangular equilateral triangle

Explanation:

• Isosceles triangle: A triangle with two equal sides. Here, two sides are \(4\mathrm{cm}\), so it is isosceles.
• Right - angled triangle: The sum of angles in a triangle is \(180^{\circ}\). Given two angles \(45^{\circ}\) and \(45^{\circ}\), the third angle is \(180-(45 + 45)=90^{\circ}\). A triangle with a \(90^{\circ}\) angle is right - angled.

Answer:

right isosceles triangle
