ICSE Class 7 Maths Properties of triangles
|
All sides are equal
Let, \\({\\angle}1= x^{\\circ}, {\\angle}2= (x+10)^{\\circ} and {\\angle}3= (x+20)^{\\circ} \\). Sum of all the angles of a triangle is \\(180^{\\circ}\\).
exterior angle = sum of opposite interior angles
Think about the size of the angles in different types of triangles.
Total sum of angles in a triangle is\\(Â 180^{\\circ}\\)
Use exterior angle property.
\\(PQ^{2} = OP^{2} + OQ^{2}\\)
Draw MN \\\\ AQ, MN \\\\ BR and use exterior angle property.
In a right angled triangle,base = 12= distance b/w thier ground points, altitude=difference in heights = 34 -29, hypotenuse = distance b/w tops
let the angles be 4y, 3y and 2y
