Answer:
Step-by-step explanation:
An isosceles triangle has two equal sides and the two opposite angles to the sides to be equal.
Given that; RP = RS, RQ and PS are common,
RP = SQ (opposite sides of parallelogram RPQS)
PQ = RS (opposite sides of parallelogram RPQS)
ΔRPS = ΔQPS (congruence property)
Thus comparing triangles PQR and SQR,
= 
(similarity property)
<PRS = <PRQ + <SRQ (bisection of included <PRS)
<PQS = <PQR + <SQR (similatity property to <PRS)
= 
(congruence property)
But, SRQ = PQR
So that;
Therefore by Side-Angle-Side (SAS), the required additional fact is:
Answer:
area = 39.25 cm²
Step-by-step explanation:
The top and bottom area of a cheese wedge is shaped like a sector of a circle so finding the area of the top surface of this wedge is same as applying the area of a sector.
Top surface area(sector) = ∅/360 × πr²
where
∅ = central angle
r = radius
Top surface area(sector) = ∅/360 × πr²
area = 45/360 × π × 10²
area = 1/8 × 100π
area = 100π/8
area = 100 × 3.14/8
area = 314
/8
area = 39.25 cm²
