HGI is congruent to JIG due to the Side-Side-Side congruence theorem.
This theorem states that if the three sides of one triangle are congruent to the three sides of another triangle, the triangles must be congruent.
In order to create these triangles, we must draw a diagonal in this triangle. This will be a shared side between both triangles.
A rectangle's opposite sides are congruent; this means the top and left sides, which are part of one triangle, will be congruent to the bottom and right sides, which are part of the other triangle.
This gives us all 3 sides of both triangles congruent, and therefore the congruence theorem applies.
Multiply the number of cm in one inch by number of inches in one foot by number of feet in one yard.
2.54 x 12 x 3
Answer:
r= 1.69
Step-by-step explanation:
Answer:
24 cm^2
Step-by-step explanation:
Find Side Length:
20cm/4 = 5cm
Use x:
First Diagonal - 4x; Second Diagonal = 3x
Pythagorean Theorem:
a^2 + b^2 = c^2
Use Pythagorean Theorem:
a = 1/2 of First Diagonal
b = 1/2 of Second Diagonal
c = Side Length
2x^2 + 1.5x^2 = 5^2
4x^2 + 2.25x^2 = 25
6.25x^2 = 25
x^2 = 4
x = 2
Formula for Area of Rhombus:
1/2 * First Diagonal * Second Diagonal
Use Formula for Area of Rhombus:
1/2 * 4(2) * 3(2)
= 1/2 * 8 * 6
= 4 * 6
= 24 cm^2
Yes, it has an even exponent/only even exponents
