please explain 10th std NCERT
Triangles lesson chapter notes​

Answer 1

Step-by-step explanation:

Scalene Triangle – All the three sides of the triangle are of different measure

Isosceles Triangle – Any two sides of the triangle are of equal length

Equilateral Triangle – All the three sides of a triangle are equal and each angle measures 60 degrees

Acute angled Triangle – All the angles are smaller than 90 degrees

Right angle Triangle – Anyone of the three angles is equal to 90 degrees

Obtuse-angled Triangle – One of the angles is greater than 90 degrees

Similarity Criteria of Triangles

To find whether the given two triangles are similar or not, it has four criteria. They are:

Side-Side- Side (SSS) Similarity Criterion – When the corresponding sides of any two triangles are in the same ratio, then their corresponding angles will be equal and the triangle will be considered as similar triangles.

Angle Angle Angle (AAA) Similarity Criterion – When the corresponding angles of any two triangles are equal, then their corresponding side will be in the same ratio and the triangles are considered to be similar.

Angle-Angle (AA) Similarity Criterion – When two angles of one triangle are respectively equal to the two angles of the other triangle, then the two triangles are considered as similar.

Side-Angle-Side (SAS) Similarity Criterion – When one angle of a triangle is equal to one angle of another triangle and the sides including these angles are in the same ratio (proportional), then the triangles are said to be similar.
