Question

Construct a Triangle RST with sides RS = 4.5 cm ST = 5.4 cm RT = 6.4 construct similar Triangle MNU. RS / MN = 2/1​

Answer 1

Answer:

Given : A triangle RST is constructed in such a way that RS = 4.5 cm,

= 4.5 cm and angle TRS = 50°.

To Find : Name the type of triangle?

Solution:

RS = RT = 4.5  cm

∠ TRS = 50°.  ≠ 60°

Hence given triangle is Isosceles triangle

समद्विबाहु त्रिभुज

समद्विबाहु त्रिभुज  एक न्यूनकोण त्रिभुज होती है

Isosceles triangle is always an acute angles triangle

Acute angles triangle - all angles below 90 deg

right angle triangle - one angle 90 deg

obtuse angled triangle - one angle above 90 deg

Equilateral  Triangle - all sides equal

Isosceles triangle - two sides equal

Scalene  - none of sides are equal

Isosceles right angled - one angle is 90 deg and two sides are equal

Answer 2

Answer:

one rational number=4

second number =x

product= -5/8

4* x= -5/8

x=(-5/8)*(1/4)

x= -5/32

therefore

second number=x= -5/32
