Answer:
Robert Recorde.
Step-by-step explanation:
Robert Recorde was a Welsh known for vast knowledge and experience in the field of mathematics and physics. He was born in Tenby, Pembrokeshire, Wales during the Medieval period (c. 1512).
Robert Recorde was famously known for his work in the field of mathematics and most especially, the invention of the equal to (=) sign. He introduced it in his book titled "The Whetstone of Witte."
<em>Hence, Robert Recorde was the first english mathematician who first used the modern symbol of equality in 1557. </em>
Answer:
Step-by-step explanation:
Since each side of a line is 180 degrees, we can write the following system of equations:
Add both equations to solve for 
:
Now substitute 
into 
to solve for 
:
Finish by substituting both variables to solve for 
:
It is a segment that connects two distinct points on a cicrcle.
No it's a number that can be found in both of the factor lists.
The respective missing proofs are; Alternate interior; Transitive property; Converse alternate interior angles theore
<h3>How to complete two column proof?</h3>
We are given that;
∠T ≅ ∠V and ST || UV
From images seen online, the first missing proof is Alternate Interior angles because they are formed when a transversal intersects two coplanar lines.
The second missing proof is Transitive property because angles are congruent to the same angle.
The last missing proof is Converse alternate interior angles theorem
because two lines are intersected by a transversal forming congruent alternate interior angles, then the lines are parallel.
