The missing steps are each right angles and .
Solution:
Step 1: Given data:
Step 2: In the two polygons,
and
(Each right angle)
Step 3: Given
Step 4: By third angle theorem,
If two angles in one triangle are congruent to the two angles in the other triangle, then the third angles in the triangles also congruent.
Step 5: By the definition of congruent polygons,
If two same shape polygons have all the angles are congruent and all the corresponding sides are congruent then the polygons are congruent.
Hence .
Therefore the missing steps are each right angles and .
Answer: b
Step-by-step explanation:
Answer:
Two isosceles right triangles. and
Step-by-step explanation:
The length of one side is:
An isosceles right has two sides of identical length, which are both legs and perpendicular to each other. There are two possibilities:
Range= biggest number - smallest number
so,
67 - 39 = 28
Answer:
It should be in between 8 or 9
