एक आयत ABCD ज्यामध्ये BC = 24, DP = 10 सेमी आणि CD = 15 सेमी
CP = 15 - 10 = 5
वापरलेली संकल्पना:
त्रिकोणाची समानता
जर दोन त्रिकोणांमधील संगत कोनांची मूल्ये समान असतील तर त्रिकोण समान आहेत असे म्हटले जाते
जर दोन त्रिकोण सारखे असतील तर त्यांच्या संबंधित बाजूंचे गुणोत्तर समान असेल
गणना:
∆ADP आणि ∆QCP मध्ये
∠ADP = ∠QCP (दोन्ही 90° आहेत)
∠APD = ∠QPC (अनुलंब विरुद्ध कोन)
AD||BQ म्हणून, नंतर
∠PAD = ∠PQC (पर्यायी कोन)
तर, ∆ADP आणि ∆QCP हे समान त्रिकोण आहेत
आता,
AD/QC = DP/CP = AP/QP
∆APD मध्ये
AD 2 + DP 2 = PA 2
24 2 + 10 2 = PA 2 (AD = BC एका आयताची विरुद्ध बाजू)
PA = 26
⇒ 24/QC = 10/5 = 26/QP
⇒ QP = 13
आता,
AQ = AP + PQ = 26 + 13
⇒ ३९
∴ AQ 39 सेमी असेल
