Classifying Triangles by their Angles & Sides | Naming Triangles #Shorts

Sides and Angles of triangle

Is it true to say that, if in two triangles, an angle of one triangle is equal to an angle of another triangle and two sides of one triangle are proportional to the two sides of the other triangle, then the triangles are similar? Give reason for your answer.

Naming triangles by considering the measures of their angles acute triangle A triangle whose all the angles are acute is called an acute- angled triangle or an acute triangle.

Which of the following sets of triangles could be the lengths of the sides of a right angled triangle:

Classify these triangles as right, acute or obtuse angled triangle.

Name the vertices and sides of the given triangle.

Naming of triangles by considering the lengths of their sides scalene triangle A triangle whole no two sides are equal is called a scalene triangle.

If the square of one side of a triangle is equal to the sum of the squares of the other two sides then the triangle is a right triangle with the angle opposite the first sides as right angle.

''If two angles and a side of one triangle are equal to two angles and a side of another triangle then the two triangle must be congruent.'' Is the statement true ? Why?
