Answer:Only one triangle can be constructed
Step-by-step explanation:
According to the question sides given are 1m, 2m and 2m
For the possibility of a triangle the sum of the two sides must be greater
than the third side
We have 1+2>2
⇒3>2
Also 2+2>1
⇒4>1
So the possibility of a triangle is fulfilled
Only an isosceles triangle can be constructed
as two sides are equal
Answer:
Option C.
Step-by-step explanation:
It is given that,
According to SAS congruence property, two triangles are congruent if they have two congruent corresponding sides and their included angles are congruent.
Angle between 
is 
.
Angle between 
is 
.
So, 
by SAS, if
Therefore, the correct option is C.
Answer:
3:4
4:5
Step-by-step explanation:
The ratios are ...
short side : long side = 12 : 16 = 3 : 4
and for the other rectangle, ...
short side : long side = 8 : 10 = 4 : 5
_____
To reduce the ratio to lowest terms, divide each number by their greatest common factor. 12 and 16 have a common factor of 4: 12=4·3, 16=4·4. 8 and 10 have a greatest common factor of 2.
