Answer:
<em>Area</em><em> </em><em>of</em><em> </em><em>triangle</em><em> </em><em>=</em><em>1</em><em>/</em><em>2</em><em>×</em><em>base</em><em>×</em><em>height</em>
<em>Area</em><em> </em><em>of</em><em> </em><em>circle</em><em> </em><em>=</em><em> </em><em>pie</em><em> </em><em>×</em><em> </em><em>radius</em><em> </em><em>^</em><em>2</em>
Answer:
1. yes
2. no
Step-by-step explanation:
1. Yes.
since all our sides are the same, it doesn't matter which is the shorter or longer
a+a > 2a for all lengths a>0, since lengths of triangles can only be positive and greater than 0
equilateral triangles exist for a reason
2. no
a triangle will have exactly 180 degrees, no less, no more
30+70+110 >180
Answer:
Step-by-step explanation:
Two ∆s can be considered to be congruent to each other using the Side-Angle-Side Congruence Theorem, if an included angle, and two sides of a ∆ are congruent to an included angle and two corresponding sides of another ∆.
∆ABC and ∆DEF has been drawn as shown in the attachment below.
We are given that 
and also 
.
In order to prove that ∆ABC 
∆DEF using the Side-Angle-Side Congruence Theorem, an included angle which lies between two known side must be made know in each given ∆s, which must be congruent accordingly to each other.
The included angle has been shown in the ∆s drawn in the diagram attached below.
Therefore, the additional information that would be need is:
Answer:
Step-by-step explanation:
The sum of all the angles in a triangle is always 180 degrees.
Hence,
Remove the brackets:
Add/Subtract the numbers:
Subtract 103 from both sides:
Divide both sides by 7:
