Answer 1

Required Answer:-

Types of triangles:

a) Isosceles triangle:

• Isosceles triangle is triangle with two equal sides and one different side.

b) Equilateral triangle:

Answer 2

Types of triangles :-

According to the sides of the triangle, there are mainly three types of triangles. They are :-

${\large \bigstar \: \: \sf \underline{Equilateral \: triangle :-}}$

• The equilateral triangle has all the sides measuring equal. It doesn't have a greatest side nor a smaller side. All it's angles measures same.
• This triangle can be cut into three equal pieces. It has three lines of symmetry, which can cut them into equal parts.

${\large \bigstar \: \: \sf \underline{Isosceles \: triangle :-}}$

• The isosceles triangle has three sides in which it's two sides measures the same and the third side measures differently. It's two angles measures same.
• Any two sides of the triangle can be same whereas other different. This has only one line of symmetry and can cut into two equal parts.

${\large \bigstar \: \: \sf \underline{Scalene \: triangle :-}}$

• The scalene triangle has three sides in which all the three sides of the triangle measures differently and none of the angles measures same.
• This triangle can no more cut into equal parts. It doesn't have any lines of symmetry which divides them into equal parts.

According to the angles of the triangle, there are mainly three types of triangle. They are :-

${\large \bigstar \: \: \sf \underline{Right-angled \: triangle :-}}$

• This triangle has any one angle which forms a right angle i.e, it contains any one of it's angle as a 90°. This triangle has many concepts such as pythagoras theorem.
• The other two angles of this triangle measures less than 90° i.e, two acute angles.

${\large \bigstar \: \: \sf \underline{Acute-angled \: triangle :-}}$

• The acute angled triangle has all the angles measuring less than 90°. The angles greater than 0° but less than 90° are considered as acute angles.
• Every equilateral triangle has only acute angles. If there is one obtuse angle then it's not considered as acute-angled triangle.

${\large \bigstar \: \: \sf \underline{Obtuse-angled \: triangle :-}}$

• The obtuse angled triangle has any one of the angles measuring more than 90° but less than 180°.
• The angles between 90 and 180 degrees are considered as obtuse angled triangle. Any one of the angle in this triangle should be obtuse.
