00:00 - 00:59 | if each angle of a triangle is less than the sum of the other two then show that the triangle is acute angle triangle so first of all let's suppose if this is a triangle ABC and we know in a triangle the sum of all three angle of a triangle will be equal to 180 so here we have given angle A + Angle B and angle C then it will be 180 equation first and here we have given the if each angle of a triangle is less than the sum of other two let's suppose angle A is less than Angle B + angle C so here we at the angle A of both sides and Angle B + angle a less than angle A + Angle B + angle C then it will be to angle A is less than the value of this is 180 then put here and |

01:00 - 01:59 | angle a find it will be less than 180 bike to end here angle A will be less than 90 degree this is the first Anderson and we can also write ager Angle B is also less than some of the other two angles that is angle C + angle A because here we have given that is each angle of a triangle is less than the sum of other two so we can write according to the property that we have given so why we add angle view of both side then Angle B + Angle B is less than angle A + Angle B and angle C then it will be to angle be less than the value of this will be 180 then it will be Angle B |

02:00 - 02:59 | is less than 180 bike to show Angle B is a lesson in 90 degree this is the condition S and here we apply angle C is also less than the sum of other two angle angle A + Angle B and angle C of both side then it will be angle C + angle C it will be less than of angle A + Angle B and angle C so here it will be to angle C less than the value of this will be 180 so anglesey will be less than 180 bike to awaken find that angle C will be less than 90 degree so here we can see |

03:00 - 03:59 | the all three angle of a triangle is less than 90 degree so we can say that the triangle will be triangle will be acute angle triangle thankyou |

**What is triangle?**

**Sides and Angles of triangle**

**Types of triangle on the basis of Side**

**Types of triangle on the basis of angles**

**The sum of the three angles of a triangle is `180^@`**

**If two parallel lines intersected by a transversal; prove that the bisectors of the two pairs of interior angle encloses a rectangle.**

**The sum of two angles of a triangle is equal to its third angle. Determine the measure of third angle.**

**In a `Delta ABC`; if `2 /_A = 3 /_B = 6 /_C`; Determine `/_A;/_B and /_C`**

**A triangle ABC is right angled at A. AL is drawn perpendicular to BC. Prove that ` /_BAL = /_ACB`**

**In `Delta ABC;/_B = 45^@;/_C=55^@` and bisector of `/_A` meets BC at a point D. find `/_ADB and /_ADC`**
